I posted awhile back about this problem and got a little response and have since checked and replaced a few parts and still not running right. The car is a 91 NA car that i had a 3rd gen 3sge installed in by PA autosports. The car ran fine for like 3 months then all of the sudden i began to have an odd problem. The car idles for awhile until it warms up then the idle begins to jump a bit and finally the cars idle just drops to low and the car zonks out. I have replaced the isc valve and cleaned the throttle body, checked the tps and the coolant sensor and all them seem to be in spec. Just wondering if anyone has had any similar problems and if there are any wires that could cause the isc valve to stay constantly open or shut. I cant figure out what else it could be it seems dependent on the temperature of the car so it cant really be a wiring issue i dont think unless like i said its stuck open and idling fine till it gets to temp and floods or something. Just dosent make sense to me. Well any help would be great.
Thanks Chris
Ill post a video later maybe itll help explain it.
