Will do. I was planning a new one next week anyway. Got the new fuel filter on a few minutes ago, haven't driven it yet (THOUGHT I had depressurized the system by pulling the fuel pump relay with it running and waiting until it died, then trying to start it a few times... still got a healthy spray :argh:).

So while I was under there, spotted this guy hangin out with the spring. Anyone have a clue where it used to live? I'm guessing it used to go between the top of the spring and the rest of the car.

It's definitely dry rotted rubber that probably couldn't hold a pound, much less compress a spring. And the springs are original, AFAIK (I got the car with 60k, 1 owner before me, has 200k now). It's also one piece.

Any recommendations for getting my '77 280Z to pass CA Smog? (I haven't tried yet)

I'm going to convert it to electric but it needs to pass smog so I can put current tags on it while it sits on the street for a couple months before we can start the real work. Thus I don't want to spend a lot of time or money tuning the engine. It seems to run pretty well right now, (idles where it should, no smoke out exhaust, no obvious big leaks, etc) so maybe it will pass OK on the first try, but I'm suspicious of a 41 year old car's ability to do so. Searching online there are some additives people recommend but idk if those are snakeoil or what. Also most of these additives have directions like, "add this to a full tank of gas, drive it to near-empty, then refill the tank and go get smogged" but I don't even plan to drive it that much in total over the next couple months.

Had a 280ZX for a while, it seemed to run just fine but never would pass emissions on its own. Eventually we determined that unplugging two fuel injectors made it still run "well enough" to pass AZ's testing while now blowing clean as a whistle.

However, I suspect the visual on California's inspections would actually notice some disconnected wiring harnesses :v:

There are additives like this which claim to (temporarily) reduce NOx, CO, and hydrocarbon emissions. Then there's others like this which say they clean up an old failing catalytic converter (again, temporarily).

I don't know which of these, if any, I'd need. Should I just go get it smogged and see if/how it fails first?

That's what I would do, unless there's some penalty for failing. Make sure you have a problem before you try to fix anything.

order two injectors if they're cheap, disable them so they don't fire and reinsert them with wiring and all. Comedy option: source a Chrysler air pump and dilute the exhaust.

Thoughts? Skepticism? The friend-of-a-friend who showed this to me wouldn't let me pay him to install it so I'm wary it's not as reliable as I would want it to be. Also the link says it's for trucks/suvs which seems different than a yaris hatchback...



I wouldn't install a bypass module into a Yaris airbag system if I was planning on keeping any of the airbags functional. The computers are a loving expensive bitch to work on and it's super hard to trace out any faults if/when you blow something with a bad module.


My first instinct in this terrible, terrible sequence of ideas would be to buy a beater truck...but if you're dead set on this, I think the best option is completely disassembling the passenger seat, digging out all the circuitry and making some kind of enclosure for it before reconnecting it. I reckon it won't fire because the passenger weight criteria will never be met but as far as the system will be concerned, everything looks OK electrically.

A brief search doesn't turn up any specific failure penalty so I guess that's where to start.

Change the oil if it hasn't been done recently, that'll also help smog numbers if the oil's been in there awhile. And get it good and warm - take it up on the highway for a bit, romp on it a bit if you can. You need to get the cat good and toasty.

So I watched fuel trims and O2 on my first drive after replacing the filter. Long term fuel trim is rock solid stable at idle and ~2000 RPM now, instead of swinging. Short term is fluctuating with the O2 sensor at idle (basically following it... sensor goes lean, it goes up about 3%... sensor goes rich, it goes down about 3%... instead of +/- 15%).

But.... I noticed the O2 is sometimes hanging full rich while just cruising (and occasionally at idle), and when that happens, short term pulls fuel pretty hard (up to -18%). Then the pinging starts. Not nearly as bad as before, but it's there. So a new O2 sensor (and an ignition switch... gently caress you, Passlock, just glad I knew about Passlock issues and that I needed to do a relearn when it wouldn't start tonight) will be ordered when I get paid.

e: it also starts a lot easier now. i used to regularly get some extended cranking/stumbling, haven't had that happen again yet.

Since the a/c thread fell into the archives...

I need to get my a/c working again soon. We've already broken 80 a few times, which is fine without a/c, but much above that is going to get uncomfortable in a hurry. I also have a move coming up this summer, and I'd like to have it working by then.

2006 Saturn Ion. Original compressor had the clutch let go, decided it was cheaper to toss an ebay reman compressor on (STUPID STUPID STUPID). Reman lasted a week before seizing. I know I'm looking at a new compressor, expansion valve, and condenser, at the very least. Should I go ahead and add lines to the parts list?

Replacing the evaporator isn't something I really want to do; I'd rather backflush it and throw in an inline filter (the car isn't really worth yanking the dash apart on).

Rockauto has a kit that almost sounds too good - it's the condenser, expansion valve w/filter, compressor, and a bunch of o-rings, for under $300. I plan to add lines and maybe another inline filter. It sounds like that expansion valve may include the orifice tube, but if not, it's only $2 to add on. There's a couple of Four Seasons kits that are compressor + condenser (dryer is part of the condenser in my case) as well. The one I linked will be warrantied so long as I have proof the remainder of the system was flushed.

Should I pull the trigger on the bundle? $300ish (shipped) for almost everything I need sounds pretty good.

I haven't opened the system up yet to see how bad the carnage is, but I do know the schraders are seized in the existing lines, so they would need to be replaced anyway (they still open/close, but can't be unscrewed for replacement).

You should spend for the evap too. If the shraders are seized then you know its full of debris as well. Sucks, but why spend $300 plus labor only to have it fail in a day.

E: re-read that bit about the schraders. I would pull the compressor and have a look first, but plan on replacing the evaporator anyways. It looks like its a cheap enough part but a full day to swap.

You wore that on Halloween?
2010 Pontiac G5, whatever the cheapest one they sold in Canada was 2.2L I think?

I replaced the headlights on the car ~3 years ago, recently the drivers side headlight stopped work, lo-beam only. When I go to unlock the car with the remote both headlights flash and stay on, when I start the car only the passengers side comes on. If I turn the car off and unlock with the remote again both lights come on, exact same brightness. Hi-beam works fine on both lights. I went and bought a new pack of lights, but I'm hesitant to open it if I don't have to, I'm having trouble believing the light burned out so quickly. I should be able to see if the filament is burned out if I take the light bulb right? I already tried replacing the fuses for lo-beams on both lights.

There's a good chance it uses the high beams at reduced power for indication when you unlock / etc.

What kind of bulbs did you use? A lot of aftermarket bulbs that claim to be brighter, do so by greatly sacrificing lifespan.

If the filament has catastrophically failed and fell off, yes, but I've seen plenty of bulbs that I would have sworn were fine from a visual check that were actually burned out.

You could swap bulbs between the two housings and see if the symptoms follow the bulb or the housing.

A lot of times, you can flick the rear of the bulb and it'll magically work again for the next two weeks.

Other times the entire thing explodes inside your headlight assembly leaving shattered glass forever inside the lens.

This guy, the filler tube:



Is nowhere to be found in this van. Everything else under the hood is the same. I can see where that tube goes that there's a rubber hose with a PVC pipe cap hose clamped into it as a plug. Rockauto doesn't have them, nor anywhere on google. GOD DAMMIT, PREVIOUS OWNER.


e: the hose that goes to the side of the air cleaner in the pic is also missing, so I guess this thing is just sucking in air from the doghouse. There's still a filter involved, so does that matter? I mean it drives and runs but I assume they didn't engineer the hose in for no reason.

(Expect a lot of these posts as I discover more PO retardation I guess)

If you still need one try calling the dealer, they've been the only place I've ever been able to find them when they are missing/broken short of the junkyard and at least Ford was selling them for like $13. I would also suggest replacing any missing parts, usually vacuum lines connected to the airbox are either emissions or sensor related. Having an 85 dodge myself I know they may be no help at all but it's worth a try.

If all else fails, you should be able to contact a dealer and get a new key based on the VIN. It may take a week or two and cost a couple hundred bucks.

A locksmith should be able to pick the ignition switch.

There are also options that involve hammers and screwdrivers.

How deep in the garage is it (i.e. can the tow driver get to it at all where it's at), and is it being towed because it's getting repaired, or because it's being donated?

A set of dollies under the rear wheels would let you roll it out, and the tow driver probably has these anyway. Or they can just drag it if there's no fucks to give about the car.

If you don't want to drag the car but don't want to pay to get a key remade, you can probably disconnect the shift linkage from under the car and put the car in neutral that way. Or you could pull the driveshaft, but you'll lose fluid out of the rear of the transmission. These also assume you aren't concerned about the steering being locked.
