Well, I pretty much believe him. He described what he did in much more detail than I put down. And how is anybody supposed to verify actions like that, anyhow?

Shawnee123 · 04-21-2010, 12:32 PM

omg

Again, bad joking on my part.

I'm gonna quit for the day (well, probably not.)

Cloud · 04-21-2010, 12:34 PM

Well, I can ask. I can ask for the parts that were replaced. I can read the description on the invoice. But otherwise, I pretty much have to take their word for it. Do you have a better idea?

Shawnee123 · 04-21-2010, 12:37 PM

No I don't have a better idea.

Sigh.

Mostly, I get so sick of everyone waiting around like spiders for any slip-up they perceive from tw...no, not you. So, it followed that mechanic man said "yeah" and...

Nebber mind, again.

Cloud · 04-21-2010, 12:40 PM

spiders! spiders! get them OFF me!

(runs screaming into the night. . . . okay, the afternoon)

Put some electrical tape over the little lights on your dashboard.

Issue resolved 04/21/2010. Left vm for customer, no cb. Closing ticket.

Cloud · 04-21-2010, 01:00 PM

that would be nice, if 1) the engine wasn't acting up; and 2) I didn't have the inspection sticker problem

guy called and said that he's still getting the same code, and so he's ordered ANOTHER PCM to be installed next week. I guess we can only try, but I'm feeling very discouraged.

Cloud · 04-21-2010, 03:11 PM

which is why I so dislike car problems. blecch!

Very well, sir, we don't know what he meant by "check voltages". But I'd wager he did what the service manual told him to do.

'Check voltages' is about disconnecting the valve from its connector. Then measuring voltage on that connector. It says power is provided to the valve. We already know that. The valve works most of the time. That measurement does nothing to find an intermittent - only identifies a constant failure.

Moving on to what is known - new information for Cloud. IACV fully opens when the car starts. That is why a car is started without pressing the accelerator. The IACV valve does that automatically. If the IAC valve does not open, then the car would not idle at a higher rev - ie 1200 RPM. Therefore that valve operated normally when the car first started.

As the car gets warm, the valve remains mostly closed. But if a warming valve gets stuck, then the car will run rough (too lean) until that unpowered valve eventually frees itself; and closes.

Of course a fully depressed accelerator would make that stuck valve ‘not apparent’. So yes, what is done to make ‘roughness’ no longer happen would be a critically important symptom.

Cloud · 05-06-2010, 01:21 PM

yep, it's still on. After a computer update; then a replacement; then a replacement for the replacement.

I have very few options. I can keep throwing money at it, (and NO, sorry, I'm not going to start messing around under the hood myself) and hope someone can fix it. Or I can just drive it until it dies, until I need my new inspection sticker (in August), or I feel ready to get a new car.

yeah. Makes it harder to get a good used trade in.

take the bulb out, and trade it in
