For some reason when ever my car reaches it temp. My car car starts to idle high around 1500 sometimes 2000. Ive changed the tps, egr gasket, replaced the IAC valve 3times, and still when it gets to temp it idles high. Ive also checked all the hoses there all in pretty good shaped, what else do I need to look into, also when its in park or neutral my side tach gauge goes crazy but once I put it in drive it goes back to working perfect , so confused :BangHead:
