97 Galant Low Idle/Stall Problem
New to the forums but it seems like a fantastic resource. Nice to see people using the web for something helpful and productive!
Here's the story:
Driving home from work Monday and the car overheated. First time issue with no warning at all. Limped it home stopping occasionally to add water (fun in the Texas Summer heat - :icon_rolleyes:).
I believe the culprit was the thermostat but it busted a seam on the radiator when it went. So new thermostat, gasket, radiator.. flushed, bled & filled and the temp is now good to go.
Unfortunately the idle isn't. When I first fired it back up after all the above it was idling low @200-300. Couldn't run the AC at all without it dropping to 100 or stalling. Disconnected the battery and did the idle rev up and drop down thing to reteach the ECM and drove it around a good bit. Seemed to help and idle steadied out, even with AC on, but was still a little low (@400-500 but dipping a little at stops).
Got up this morning to drive to work and back to square one with the idle. @200 or so with no AC, won't run with the AC on.
Now I can two foot it (one on the brake & one on gas) and get it to idle steady with or without AC.
I guess my question is would overheating damage the IAC? Temp Sensor?
I'd rather not have to replace the IAC or even mess with the throttle body for that matter, so simple solutions & suggestions are obviously preferred. This car isn't my pride and joy like with most of you guys, it's a daily driver I bought just for a long commute to save gas vice driving my truck.
Also read where someone was having idle problems and adjusted the throttle cable to offset it... good or bad idea?
Sure would appreciate any help you guys can offer.
Thanks.
