Re: Fast idle on a 98 4.3 Blazer ?????
It is weird.
During the day just driving around in traffic, it will not idle down when I stop in traffic.
It will stay around 1500 till I get it stopped, then it will fall to 600.
It does it at 60 or 80 degrees.
Where is the IAC on the engine if I need to replace it?
