So hey I'll be driving along and stop at a red light. Then sometimes, mostly when its hot hot hot (the weather not my temp gauge) my car will idle low then normal low then normal low and then die... i just replaced my fuel filter and sparks, wires cap and rotor good? could it be battery? the terminals are clean. So yah any help would be good.

 

vaccum leak probably.....do a vaccum test, fluxuating idles are a pain in the *** You're probably sucking air from someplace

 

Damn, same thing happened to me in my old hatch. And I did also have the iridium spark plugs But I don't think it's that. I do live in Riverside co, it's about 115 degrees on a good summer day My car used to sound like it had a fat *** cam. Is your timing right on? ecu chipped? Tried another IACV?

 

hmm timing last time i checked i think it was advanced not sure tho. vacume test what do i need to perform one?
