does anyone know the voltage the iacv should be getting?

DaveF

it should recieve a 12v key on sig from the yel/blk. and on obd1 ecu's the blu/blk runs to pin #a9

so having a poor alternator would affect voltage to the iacv? i know its my iacv now, so i just have to figure out why its doing this. thanks

DaveF

check for a bad connection @ the dead end plug on the left side of the engine bay

dead end plug...hmmm..can you be more specific? i still have the idle surge. i got a new map sensor, tried out a friends ecu and chip. it seems to come and go now. also it seems to only surge 3 times and then steady off. any ideas?

DaveF

possible vacum leak around the throttle body, make sure your gasket covers the entire outer perimeter, or you are sure to have a problem.

maybe the FITV is a bit loose if you happen to have that style TB.

yep im checking for vacuum leaks today with soap and water. what was that plug you were talking about? what i dont understand is why it only happens sometimes....ususally after i have taken it over 5000rpm and or once its warmed up. i never get it on a cold start and for at least the first 10 minutes of driving.
