Cuts off after a cold start, sensors?
Hey,
My 86 IROC cuts off about a second after cold starting. If I hold my foot on the gas, I can put it in reverse, shoot backwards, put it in park (dies) start it back up, go foreward until it realizes it works, and then drive normally. The idle at park is about 700 rpm, which seems low (I remember it should be around 1200 on these cars? in PARK).
I have cleaned the IAC and its surrounding valves and throttlebody. So... what should I do? The car has a new starter, this problem has been happening off and on for as long as I've had the car, but as of yesterday it happens just about every time I start the car.
Soo... IAC? MAF? Link me to good replacement parts, but I dont know whats broken.
EDIT: I am getting trouble codes from the engine, ill go read them now.
EDIT: The codes I am getting are 32 and 34 (along with the usual 12)
