Hey everyone I've had this problem for about two weeks now, I posted in the L36 forum and got few responses and my problem has gotten worse, so here is try number two....
This first started, I'd be sitting at a stoplight and the rpms would drop to 400 then shoot up to 1500, then level out, then about 30 secs later do it again. Lately the car has been staling out. It will stay running If I give it gas, but If I let off the RPMs bounce between 400 and 1500 then the motor dies again...
Tests I have ran,
Ran in Speed Density mode (unplugged MAf) problem still exists
Replaced IAC, problem still exsists
Checked Batt. voltage while car running, Solid 14.65 V
Second Tank of gas, so gas presumably ok
Checked spark(removed both wires and listened for arck between posts)
Fuel pump does prime, and Shop I took it to said there were no fuel pressure or vacuum issues
I am out of Ideas
Any help is appreciated
