Help me get the car to idle.... Okay, I have the idle set at 950 in park and 850 in gear with LS1 Edit. I had the idle set screw set way up before to get the car to idle without programming. I turned it back down since I have Edit now, and I can't get the car to idle. I realize that this is probably because the engine isn't getting enough air now. Should I drill the TB hole bigger or raise the idle screw up again? I have the TB hole slightly bigger than stock now. Thanks!
Re: Help me get the car to idle.... Yeah with that cam I think you need to drill the hole a lot bigger. Remeber, drilling the hole and using the set screw don't do the same thing. Turning up the screw increases air and idle speed at the same time. It is better to set the idle speed with LS1edit and control the idle air with the hole; that way you have independant control over both parameters. Just step drill the blade until your IAC counts come down into the 30's.
