Re: Inconsistent high idle - very strange - Help?
Having the same issue but mine is like 1200. Tightening the BISS screw didnt help because on occasion it would idle at around 450rpm vs 750ish. Im convinced its my IAC. Altho, im going to check a few other things first. Waiting on a pressure tester now and then im probably going to buy a brand new IAC instead of using junkyard ones.
Also, it went away when i dropped my base timing down to 3 degrees. I dont know why.....but i like my base timing at about 8 degrees and i dont run but 12psi on 93 so i set it back and put up with the idle.
Ill keep this thread updated if i fix it.
