Seems to me that if it was a fuel supply issue, it should get worse under load / more throttle, not better - more throttle would just mean more lean.

To reiterate the first reply of the thread - don't just throw parts at it. Do plugs on it if they're due and you don't want to do it yourself, but don't expect that to necessarily solve this unless the ones that are in the car are really, really bad.

If nothing else is behaving badly (you aren't seeing low voltage out of the alternator, you aren't feeling weird power steering assist that cuts in and out) then the belt itself has probably just aged enough to start slipping. The other possibility is that the tensioner itself is failing and isn't holding the belt on as tightly as it should be. The belt just being old is more likely of the two.

In either case, it should be a very simple repair.

My 2010 Mazda 3 Sport GS is making this terrible squealing metal-on-metal sound in the front driver side wheel well. I took a video. The brakes aren't being applied at all in the video, it's just rocking. It only does this when moving at low speed below 60kph, and it doesn't make any sound when stopped or revved. Steering makes no difference.

That sounds a lot like the noise my Mazdaspeed3 made when it managed to get a rock jammed between the backside of the rotor and the dust shield.

So, I'm new to living in the north. It recently got into the negatives and so my car is indicating that the tires need to be filled up. My question is should I actually do it? I don't want them to be over inflated once it warms back up. Please advise.

Assuming you fill them properly to the value listed on the doorjamb, unless your temperatures have a 60+ degree swing in the next week, you'll have lost enough pressure just through normal use that it won't be overinflated by the time it warms up. If you somehow had a 90 degree swing in temperatures tomorrow, aside from setting some sort of world record, you'd be overinflated by about 8 PSI which really isn't that hard to deal with using a tire gauge.

Does anyone know of a mid-range gauge that shows two temperatures? I'd like to add at least a transmission temperature gauge to my WJ, and possibly engine oil as well, but I've really only got room for one 2-1/16" gauge. Digital is fine, but all I can find is really sketchy poo poo or really expensive poo poo.

I'm not even married to the idea of it being a 2-1/16" round gauge, I'd be fine with just a couple of rectangular LED displays. But if I can't find something less sketchy for a not-stupid price point, I'll probably just do the transmission temp and be done with it.

Depends on the tire. I have no experience with awful winters anywhere, but the rebranded Kumho KL61s I have on my WJ have the "winter service symbol" on them. Discount sells them as the "Pathfinder". The one day trip I took up north while it snowed this winter, it handled the snow and slush perfectly.

Plural of anecdote is not data and all, but I switched my WJ from dino oil (regular changes every 3k from new) to synthetic and have seen no leaks. The only oil getting anywhere it shouldn't seems to be an extremely small amount from the oil pressure sensor, and that was leaking before / has not increased since. It's literally just enough to leave a drop of oil hanging onto the oil filter; it doesn't ever drip onto the ground while parked.

Hook it back up, install pan, fill trans ?

All the poo poo I read says to replace it at 4L intervals, but I'm lazy.

Edit: to further explain, pumping out all the old fluid will allow a cleaner fluid overall since I'm not mixing old and new as I'm doing the "infusion" style. Secondly, I figure enough fluid residue will exist to not damage seals or clutches for the 30 seconds it takes to fully drain the remaining 5L of fluid in the converter etc.

That still seems like a long time to have the pump sucking air.

You're not going to get 100% of the fluid out on any given change; if you're really that concerned, do one change now and another in a few thousand miles.

Thanks for the code pages, that's definitely helpful! Looks like it's this one: http://en.m.wikipedia.org/wiki/GM_High_Value_engine#LX9

As far as the P0128 - really, the only two things that can cause that are either a bad engine coolant temperature sensor, or a bad thermostat. Is it running like absolute poo poo and spitting fuel out of the exhaust? Then it's probably not the coolant temperature sensor, especially since the computer should also throw a code for that too. If you really want to be sure it's not the sensor, you'd need a scan tool that can show you the actual sensor values. Then you just park the car overnight so that it's stone cold, and check the readings on the coolant temperature sensor versus the intake air temperature sensor. Both should be about equal to each other, as well as roughly equal to the ambient temperature. If the coolant sensor is reading like -30 when it's 50 degrees out, the sensor is bad.

With that said... it's almost never the sensor, thermostats are just stupid lovely little things that like to fail. It looks like it's not too bad to get to, at least - some people just take it off, some people remove a couple of hoses right above it, and at least one person decided to just pull the headlight and go after it that way. The actual replacement is just removing a hose and a couple bolts, removing the old thermostat, installing the new one, and filling the whole mess back up with fresh coolant.

When it's acting up, put it in neutral and then depress / sidestep the clutch once or twice (letting it come up as fast as possible). If it immediately gets better you definitely have some air in the system, probably caused by a failure of one of the hydraulic components.

If I were to buy a truck like that and drive it around for a while to determine how the motor is, and then do a simple gasket job would that be a decent way to get a few reliable miles out of it?

I mean, you could go through and regasket everything, but unless it's pissing fluids I wouldn't see the benefit of it. Of the ones you mentioned, the head gasket and intake manifold gaskets are the only ones that can really fail in a way that will immediately and directly impact the engine's ability to run. The rest of them, the engine may make a mess, but as long as you can keep enough oil and water in it, the engine will still run the same.

I don't think big-block Fords are particularly prone to making GBS threads head gaskets unless you overheat the gently caress out of it anyway, like any other engine, and godawful intake manifold gaskets causing massive coolant / vacuum leaks are usually a GM thing. Unless it's pissing fluid everywhere, you'd see the best return-on-investment (both cost and time) from replacing worn out suspension and interior components.

1. Usually MRSP-$10k, since it lets them say a bigger number of discounts than Invoice-$x.

Headlights in a stupid-quick runthrough:

First, lens / reflector type is independent of bulb type. There are halogen projectors and HID projectors, and yes there are even (rare) HID reflectors.

The lens type does pretty much what it says on the name. Reflector-type bulbs use a shaped reflective surface to do much of the work to take the light from the bulb (which, in general, is leaving the bulb in all directions) to direct it forward in a pattern that's both more useful and meets local lighting regulations. The lens in front may also be shaped to help direct light where it needs to go, but in a lot of modern cars it's just there to be aerodynamic, clear, and protect the light. Relatively cheap to make, but larger and the cutoff at the top of the light pattern is usually not very sharp.

Projectors use a more accurately shaped glass lens to do this work. Properly designed, you can get full bulb brightness right up to a razor-sharp cutoff. They take up less surface area on the front of the car, but need more depth, and tend to be considerably more expensive.

Halogens are just high-powered incandescent bulbs. They still work by running electricity through a wire filament until it gets so hot that it glows. Simple, effective, and dirt cheap.

HIDs actually use an arc between two electrodes to produce their light. Because you can't do that on 12V, they also have a ballast setup that generates the voltage they need to operate.

Note that because the pattern of light emitted from the bulb varies based on the bulb type (HID vs Halogen), the bulb and housing need to be paired together. Installing HID bulbs into halogen projectors is just going to blind the gently caress out of oncoming traffic.

Are you getting a check engine light when this occurs? How far past midway is the temperature gauge going?

Is the engine's cooling fan running? Even with the engine cold, if you start it up and turn the A/C on, the fan should be cycling on and off every few seconds to keep air moving over the condenser.

The fan is very loud, you should be able to hear it cycling on and off even if you have the doors and windows closed (I can on my '13 CR-V). You could always try to see if it's turning, but at least from what little time I've had to spend under the hood of my CR-V, it's buried in there a bit so it's actually quite difficult to see.

If the fan isn't running, you have no airflow over the radiator or the condenser until you move again, which will make the engine overheat and the A/C work like poo poo.

I want to try buying and mounting my own tires, but the wheels are non-OEM and I don't know their dimensions.

These are the tires+wheels that have been on it since I bought the car. What tire sizes should I be able to fit on those wheels?

PS: on a scale of 1 to "you're already blownout", how hard is it to mount your own tires?

First off - tire size is given as:

PXXX/YYRZZ

Where 'XXX is the section with in millimeters, 'YY' is the sidewall height defined as a percentage of section width, and 'ZZ' is the wheel diameter... in inches. Yes, it's stupid as gently caress.

Wheel diameter is the most important measure (you can't fudge on that at all) and those are 15" tires, so it's safe to say those are 15" wheels. Width can be fudged within reason, though the 195mm tires you have on there now seem to be fairly appropriate for whatever width the wheel actually is. Usually if you remove the wheel there will be "15x7" or something like it stamped / cast on the inside somewhere. Sidewall height (the '60' in your current tires) helps define the overall diameter of the tire, and you want to keep it as close to the factory size as possible for the sake of keeping your speedo and odometer calibrated. Because this is a percentage of width, if you go up 20mm in width, you may need to drop from a 60-series to a 55- or 50-series tire.

A little over three weeks ago, I bought a 2005 Civic sedan with 60k miles. The guy I bought it from couldn't tell me whether the timing belt had ever been replaced, so I decided to get it done immediately just in case. A day or two after I picked the car up from the shop, the belt started squealing quite a bit. I took it back and they said it was probably just the new belt stretching a bit, which is normal. They tightened it up and sent me on my way, and I didn't hear anything else until this morning, about two weeks later, when it started squealing again. It was pouring down rain this morning and I'm certain some water got splashed up into the engine compartment; if some got on the belt, could that cause the squealing? If not, and this is something I need to worry about, I guess I'll take it back to the shop and have them look at it again, but I'm not sure how long I should consider them on the hook for anything belt-related.

Your car has at least two belts - the timing belt and the accessory belt(s). The timing belt can't slip - it's a toothed belt and slipping would mean the same type of damage to your engine as if the belt had failed altogether. The squealing you're hearing is the accessory belt, and yes they can do that when they get wet. Did they replace that too when they did the timing belt? If not, it's probably old and hard and needs to be replaced. If yes, the tensioner might be failing.

Your car has a switch somewhere on it attached to the shifter linkage, that will only let the starter work if the transmission is in park or neutral. Given the intermittent nature of the problem so far I wouldn't say 100% that this is the problem, but it's quite likely. Next time it won't start in park, try starting it in neutral again. If it fires right up again that time, then you definitely need your neutral safety switch to be replaced.

Yeah, the distributor shaft is keyed, you can't put it in any teeth off (which also made it a big pain in the rear end to reinstall, it took me ages to get it oriented exactly right so that it would slot in flush). It's fine, I just need to rotate the cap another 2.5 degrees. Doing this without a timing light was always going to be not super accurate. The main thing is, it looks like the smoking issue isn't entirely due to the timing being wrong.

I spoke to my mechanic yesterday. He made a similar suggestion about thicker oil. He said he usually uses 5w30, so that's what's in the truck now; a higher viscosity will help reduce oil intrusion into the combustion chambers. There are special "high mileage engine" branded synthetics, so I'm thinking of doing a change and putting that stuff in. Plus, get the timing exactly right, and then as you said, drive the truck on the freeway for a bit, get it good and hot. The mechanic also mentioned that blue smoke could potentially be a leaking PCV valve?

It's only keyed to the oil pump so it is possible to get it off if the pump gets turned, but again if you were trying to do that you'd be off by a hell of a lot, not just a few degrees.

I would skip on any actual synthetics in an engine that old / that may have blowby, but I would probably try some of the high-mileage dino oil (like Pennzoil's stuff that's maybe $2 more than the yellow bottle, but cheaper than Ultra) or maybe just go right to 15w40 Rotella / Delo 400. Those oils kept my old 350 running even though it had enough blowby to pop the dipstick out, and was constantly spraying the valvecovers from both breathers.

The owner's manual claims the transmission fluid never needs to be changed unless the car sees severe service. I'm not sure I buy that and am thinking of having a fluid change done. Should I? Can I expect an independent mechanic to have the information they need to do it properly, or would it be better to take it to a dealer?

Also, how much should trust the oil life monitoring system? It's indicating very long oil change intervals. I have been changing it when it reaches 50% and using a synthetic oil.

The transmission fluid change on that is probably no different than any other GM vehicle (remove pan, replace filter, replace pan, fill it up with enough Dexron). It probably requires Dexron VI, but that's pretty much ubiquitous at this point. I think you'd have to try to find some old Dexron III somewhere. And yes, "lifetime" fluids usually mean "until the transmission burns up from lack of fluid changes", so I would definitely change it at some point.

The oil life monitoring, on the other hand, is usually reasonably accurate on modern cars. Highway driving is very easy on engine oil since it means you always get it good and hot. How long is "very long"? If you really doubt it, take a sample from your next change and send it to Blackstone. I'd expect they tell you it's safe to run a good while longer.
