car idles like it has a race cam???

[Coupe5oh]

thanx guys, dang this is my week for problems, anyway i cleaned the maf already, actually i think it idled better that day, if it was to be a broke valve spring, wouldnt i see it on a plug?

Im buying a 3/8 spacer, gives me a reason to pull off the upper and clean it, as well as check vac lines, my tps is an autozone one so that could be the problem, im not getting any codes except air thermactor yadda yassa....also im gonna throw in a 180 stat, if this strut installation dont burn me out, it is hot outside

btw, a broken valvspring could be it cuz i missed 4th at the track a week ago and reved the pee outta my car, but it usually takes a rev limiter hit with no problem, also the idle goes up smooth as i apply the gas, if its warm it will not stumble as the rpms go up, just at idle its like rumpity, rump.... rump.... rumpity....too much to do, but i'll sort things out, im checking harness connections and applying dielectric grease to everything i see.
