My buddy has a 91 3000gt sl and it wont idle after it warms up. If it hasnt been drivien and is cold, It will idle fine but once it warms up it wont idle, rpms drop to 0 and it cuts off. What could be causing this? Any help is greatly appreciated..
I had to replace the ECU in my stealth a couple of times. Im not saying he should start with that since it is a pricey fix...but if there is someone in the area with another 1st gen SL ECU you could swap in to see...
Something with the closed loop operation of the car? Open loop runs fine then goes into a closed loop operation...assuming a 3000GT has closed/open loop operation. Or mechanical issue?
