Question: Is there any way to get out of an extended warranty? I bought it with my car when I purchased it new last year, and feel like it's going to be a waste of money. I figure since I signed the paper work and have been paying on it still that there's nothing I can do.

As the other poster said, check your contract. The only ones I have dealt with have been issued by GM but they do contain very specific and easy-to-use buyout clauses where you can cancel the warranty and get a prorated refund, though I think it's only if you haven't made any claims on it yet.

I've checked every fuse, the Megafuse on the alternator power line, the alternator to battery link, nothing.

Turns out the megafuse was intermittently bad, due to the design having a bead of solder sandwiched in two copper curves. It tested good the other day, tested bad today. Replaced the megafuse and it ran like a charm.

Is $80 for a 4-tire dismount/remount/rebalancing about right, for putting these 225/45/18 Potenza RE-01Rs on my RX-8's stock wheels?

Firestone wants to charge $10/tire for the mounting, $4/tire for the mounting hardware (do I really need new stems?) and $6/tire for the rebalancing service. I called a couple other auto shops in the area (Sears, Discount Tire, Speedy, and a few local places) and they all want closer to $120-140 for the job.

Firestone also wants me to get a $140 "Lifetime Alignment" service.

I'm at 36K miles, and I haven't noticed any kind of abnormal wear on the tires, or any weird steering issues. They tried to tell me cars need an alignment every 6 months :rolleyes: Sure, a tire rotation every fall & spring sounds normal, but it doesn't seem like alignments should need to be done that often, right?

Edit: Surprisingly enough my dealership says they'll do the mounting & balancing for $60 total, and a one-time-only alignment would be $80.

Eintier recommended this and I was psyched about getting it. But when I searched the greater internet on how happy people were with it, there were a large number of complaints that the shop didn't do it right, or worse, that they eyeballed it, said good enough, and didn't even bother doing it. As I'd want a non-factory alignment for autocrossing, I dunno, I guess I don't have enough faith in the Firestone near me.

Sorry I'm late to this, but the chain isn't the problem, it's the tensioners. I've seen these recommended to be replaced at 100k intervals as they can tend to crack and come apart. It's not cheap, but failure to do so may result in damaged valves. Does the sprocket end of your motor sound like a rock tumbler? If so you may be getting near the service life of these guys. The best time to replace all of them is when you're having the clutch done, as I believe the trans needs to be dropped to get to the lower ones. Good DIY:

Backstory: I've been planning to go up to Maine for weeks now, around a 400 mile drive both ways, and I finally decided to do it this weekend. I was going to take my mom's car (an Audi A6), until it magically broke down and now needs 2 catalytic converters replaced and an oil leak and a transmission fluid leak fixed, totalling $5000, a repair I assume will take more than 3 days.

So now I'm hosed. My only option is to take my daily car, a 2001 Ford Taurus with around 92,000 miles on it. It's never really been used to drive such a long distance, just locally. Is it a bad idea to suddenly drive it 400 miles over a span of 3 days? Will it incur the wrath of the car gods?

Long drives are usually easier on cars than short drives. As long as the car is in OK shape now, it should be fine for the trip.

But it wouldn't hurt to check your oil level, tire pressure, coolant level, etc. before you leave. It should all be checked regularly anyway, but many times it is not.

My transmission has been acting weird lately. The car is an 05 Elantra with a 5 spd, 38k miles. When putting the car in reverse once and a while it will grind the gear with the clutch floored. The clutch doesn't slip, so its not worn. Also recently downshifting has become harder, it won't just slip into gear. No grinding here. My first thought was the syncros, but could my clutch cable just not be tight enough? After looking in the manual it looks like there is too much play in the system.

If it is just the cable, will the shop adjust it under warranty. If not, would it be hard to do with instructions? If its the syncros I'm hosed, but that should be a warranty item.

It's a 99 Ford Escort LX with the 2.0ltr SPI engine and a 5spd transmission.

Sometimes when driving, typically after shifting(when I am reapplying the gas), the car will chug. It will be down on power and there is a ticking/tapping noise from the engine. If I clutch in and rev it a few times the ticking/chugging will go away and it will act like nothing happened.

My first thought is that could it possible be an injector screwing up?

I recently bought an F250 with the 7.3L Powerstroke diesel to use as a beater truck.

I've been looking into basic mods for it to improve responsiveness and mileage, and one of the more popular ones seems to be swapping out the diaphragm wastegate actuator for a mechanical actuator.

While researching the mod, I've come across several disputes on the viability/reliability of wastegate control via drive pressure, which is what the mechanical actuator uses, versus boost pressure, which is what the diaphragm uses.

Anyone have an opinion on this subject? I'm not familiar enough with the empirical operation of turbocharged engines to make a judgment call here, and both sides have compelling arguments.

Stupid drivers always breaking car, Gronk fix car...
Every production turbo car ever (minus a few examples like the Porsche 944 turbo, Audo 20V turbo, etc) uses an internal wastegate actuator. There are some benefits to external wastegates, but I don't think I've ever seen one on a diesel. Even rigs with real engines double your displacement still use internal wastegates.

What do you mean mechanical? They are either internal, external, or use a VATN system for boost control. Internals use a diaphram pushing a rod and flapper, externals pull up on the diaphram and removes a valve from a seat, and VATN changes the way the gases hit the turbine wheel.

It could cause it to chug and almost die when there is little to no load on an engine (when you depress the clutch or shift to neutral, for example.)

The wastegate on this turbo is internal, and I'm not talking about changing the wastegate itself, just the actuator. The diaphragm type uses a canister with a diaphragm and spring, with a small line feeding intake air to one side of the diaphragm. The intake pressure on the diaphragm compresses the spring, which moves the arm that's attached to the wastegate on the turbo.

The mechanical type doesn't have a diaphragm or an intake pressure line. It just uses a spring, tensioned against exhaust pressure (drive pressure) to hold the wastegate closed, and is tuned to allow the wastegate to open once drive pressure reaches a target level.

The supposed disadvantage to the diaphragm actuator is that, because there's always intake pressure, the wastegate never closes completely, allowing a constant leakage of drive pressure that causes the turbo to spool more slowly.

The maker of the mechanical actuator claims that, because it uses a cammed lever and spring, the wastegate will remain completely closed until it reaches the drive pressure to which the actuator is tuned, thus eliminating drive pressure leakage and improving turbo response.

Detractors of the mechanical system claim that it's not as precise, since depending on conditions, intake pressure can vary despite a constant drive pressure, and that it creates a risk of overspooling the turbo that doesn't exist in an intake pressure-controlled system.

Users of the mechanical actuator claim that it's plenty accurate in real-world application, and make the point that the diaphragm actuator uses drive pressure as a failsafe, in that should the diaphragm or intake pressure line fail, the wastegate will still open under drive pressure eventually. In fact, some people with this engine have taken to disconnecting the intake pressure line from the diaphragm and allowing drive pressure to do the job, with the caveat that it's very difficult to tune the diaphragm actuator to obtain precise pressure control.

This is a "tell me what kind of car to get" post. I didn't see a "recommend a car for me" thread, and figured it fit the definition of a stupid question, so here goes.

I currently have a 1998 Acura Integra RS. It's served me pretty well, but I'd like something a little newer and nicer, and I'd like to sell the Acura while it's still got some value. My budget is somewhere around $20k, and I'd like something that isn't more than 4 or 5 years old... preferably something I could get as a "Certified Pre-Owned" or something like that with a warranty.

I really like the Audi A4, the new Volkswagen CC, and the Acura TL. Basically I'm looking for something in a 4-door, with some nice "luxury" type features, that's reliable and moderately peppy. It doesn't have to blow the doors off anything, I'm just using it to commute.

So what are my best options? And what else do I need to consider when researching/buying one of these? I know this is a very broad, open ended question, but any advice is appreciated. Thanks!

Yeah don't bother trying to switch to auto HVAC. Probably be pretty drat expensive and who knows what body control modules you'll need as well.

And I would just stick with using the AC. Yea it'll kill mileage but is sweating your nuts off worth saving a dollar or two every fillup?

They can, they can also tell how much space you are leaving between you and the car in front of you, and ticket you for not leaving enough space.

They can however also make a mistake, or even straight up lie.

Honestly, the odds of a cop lieing on a petty traffic violation regarding the number the radar gun gives is basically zero baring other circumstances (say, you just hosed his mom).
Error is far more likely. And i'm not argueing this from a "cops are honest" platform, just why go to the work and take the risk (getting caught perjuring yourself means a cop is fired and will never be hired again, he's useless.) when there's some other guys speeding.

And yes, reading your speed going the other way is very easy.
Note that these are generally always on units so you can get them coming from some distance on a detector.

I'm guessing for safety reasons. If you encourage people to put a bunch of stuff on top of the dashboard, it can start flying around the cabin if you get in an accident, or even if you need to do some quick steering. And anything flying around (especially right at the driver & passenger head/neck level) can be dangerous. Plus if you've got all those fancy cupholders & accessory trays, who needs to put stuff on the dashboard?

A new truck doesn't have any electronic boost control? Holy poo poo talk about dark ages. I swear most trucks do, every turbo car picked up on that nearly 2 decades ago, and big rigs have had it for a few years. My EBC was made in 1988, and was widely available.

I guess a flapper-based pressure relief would work, but why make lovely engineering worse but adding stupid redneck on top of stupid ford engineer?

Get a electronic boost controller, put it in on, and then you have the actuator closed until it reaches its target pressure, and you can turn a knob on the controller to adjust the maximum pressure it will hold.

I see what you mean but there are only two spots for anything that isn't a drink. Sometimes you need a flat surface if you are on a road trip with friends and you need space to put maps, books, ipods, food, etc while you are on the freeway.

Right in front of the driver is a small compartment you can put stuff in. It seems like it was specially made for maps and other things you might want to keep on the dash, and it's a pretty cool idea in my opinion since it both gives you space and keeps stuff from flying at you in a crash. It's sort of like a more convenient glove box, but they move the speedometer and everything to the center console which takes some getting used to. I suppose it was phased out, though, looking at the '09 Quest:

I find this under the OEM section, but I'm not sure if this is a European only feature or if it's a factory option. On the GTI, you can replace the air vent on the top of the dash with a tray.

Personally, I don't need things flying around so I'm never going to install one, but it's a fairly popular mod. If I ever needed more space (besides my glove box, arm rest, cup holders, "ash try", door slots, or pockets behind the seats), I could always get drawers underneath my seats or another cubby hole to the left of the steering wheel.
