Well hello there everyone I have a 2001 chevy Monte Carlo ss and I'm having issues with a high idle and just before that it was stalling ? I've cleaned the maf sensor and just recently replaced the iac valve ? Last year I replaced the plugs and wires and it ran good for a bit ? Any ideas as to what it may be ? And is there anyway to reset the iac valve ?

 

have you tried cleaning the throttle body? I know on my old eclipse when I cleaned my MAF I unhooked the negative cable from my battery for 15 mins and its suppose to reset some things to do a (relearn) so that it will learn the new idle
