Default Re: Hi Idle 1K RPm

If your car is a 1990 GM had a up dated prom for high idle and slow idle recovery, check service bulletins, I used one and it worked. There is a Registry thread about how to make the PCV valve holder out of copper fittings, I did it and it worked great at about a cost of $15 and two hours work.
