Another High Idle Question (have read a few..)
So I get high idle in park and neutral only after driving for a little while. I also have been getting a hard start.
High idle happened for about a week, then hard start, so I cleaned the Throttle Body and the AIC with cleaner and also sea foamed the engine. I threw some fuel injector cleaner in a full tank too.. just for fun.
Problem went away for about 2 weeks and now is back, maybe even a little worse.
Mainly wondering why being warm would create the High Idle; it only hard starts when cold (kindof obvious)
2 more things: the exhaust system fell off while on the highway (during problems, before cleaning), so cat muffle etc..
and I haven't reset the trouble code yet- was going to do that today, but forgot my laptop at a buddies.
I think most likely its the TPS or AIC does TPS make for a hard start? It seems strange that the high idle doesn't come on until after Iv'e been driving instead of right away.
