no, as consult, datascan, etc, etc only really reports on ecu activity. The signal is fine from the ecu, the solonoid itself may be a little slow, only way to really prove, disprove is swapping out to a known good one. I think my zed does the same, maybe, not sure, as it's being a royal PITA at the moment.
whats the best way to clean the IACV? should be pulled out of the car completely? might give this a try myself. Interesting that you car went bad after introducing the leak psyco, must be a completely different problem to me in that case.
pull it off, and dismantle it. Clean it with degreaser, thinly grease with some hi-temp automotive grease the plunger/rod, and reasemble. Check that the solonoids are working by crossing 12v across the terminals, should hear a nice "clunk", throw it back on. If your careful removing it you can reuse the paper gasket between the unit and the plenum.
i cleaned mine like that yeah, might give it another try on a sunny day and see what happens, as its shitting me, off topic, whats wrong with yours, need a hand?
Just buy a sheet of gasket paper from Auto1 or wherever and cut out the shape you need. It's like $5 or something
This, I don't have. (long corrugated piece with the yellow arrow). Is it part of the stock airbox? it looks somewhat useful
Its supposed to attach to the stock air box, I just rolled mine up and stuck it under the front bar. Its just plastic.
Not to worry, it would have been removed with the stock airbox, I don't even have the mounting bracket you're holding your pod filter by. If anything, I think that would actually block air from flowing through the thinner gap in the front bumper, forcing the air down and then through the rad. The only other though that comes to mind is that it's a splash guard?
Yep I just purchased a new one today, that old one is pretty stuffed. Going to install it tomorrow and see if that makes a difference.
Update: Ok so i've replaced the air filter with a new one, have also cleaned the MAF and sprayed some electrical spray on the connectors. Still having the same problem, what I've noticed is that when I give it a bit of acceleration it will happen. At low speeds it seems ok. Something to do with air/fuel mixed maybe?? I don't know... Could it be a vac leak, too much air escaping? It seems to idle OK, though it does go up and down a little bit from 800-900, what would cause that? IACV? Any other suggestions would be great, thanks.
Analysis of the IACV system would reveal more: Question to the gurus/knowledgable: 1. The Idle Air Valve is the only aux air system functioning when the present conditions are met: The car is warm, the air con is off? 2. The Idle Air Valve stays at the same % when revving? Does it ever change value other than to regulate air at idle? If the above two statements are correct, then the idle air regulator is probably not the cause. 3. The AAV valves - There are two of these, one attached to the IAV and another inline after the IAV. Do these two valves, if on, stay on when you rev? or do they turn off the moment you hit the accelerator? These questions could be easily answered by datascan, but I'm at work at the moment so... Cheers Greg.
