    Default High idle

    I noticed that lately my idle is at 15000 and doesn't drop until I come to a complete stop, is there a way to adjust that?

    15,000!!!




    Check for vacuum leaks. Car should have a high idle (1000-1250) while the car is moving, not dropping down to ~800 until you come to a dead stop.

    Once I did the cam swap and added the blower my high idle has been consistently 1500 RPM. Not saying it's right or wrong, just that I'm in the same boat as you.

    It just seems weird like it's racing till I come to a stop then drops to about 900
