hmm, id say bad sensors somewhere or bad ecu wiring, but that is pretty puzzling...hell just buy a standalone, then u can tune it all lol. sorry dont mean to take your situation lightly. good luck with it!

How hard is it to get to the ecu, I have a spare one from my parts car that I can put in it. Same year engine and tranny.

should be on the pass side under the dash or kick panel. i think its behind the glovebox area, shouldnt be too hard to get to.

go get a haynes manual for it, 20 bux well spent. itll tell you where most of that craps at.:bigthumb:

I've got a Haynes manual but couldn't find the ecu location.

What would be a good standalone to buy?

I switched out ecus and it ran but not great. It revs up to 2500 rpms before idling down to 400 rpms and then barely runs. Giving it gas it has a lot of hesitation.

Check the tps and wiring

I checked the tps and the wiring to it. I also tried adjusting it while it was running, but it didn't get any better.

I had a similar problem. With mine I could not keep the rpms at 1500, and when I took my foot of the gas pedal the idle would fluctuate between 400 and 600 rpms...
I had i bad IAC.

cfurlan 04-21-2011 08:24 PM

I will try and put a spare iac in today to see if there are any changes.
