Ok yesterday I thought I had solved problem with high idle and rpm hanging between shifts by replacing IAC TPS and reseting idle and adjusting tps, the car ran perfect. Ok new day come home from lunch start car and idle starts high then falls to about 900-1000rpm...seems good runs 2minutes and all good. THEN I touch the gas to rpm start rising to about 1500 and hang, I decide to drive it and rpm are hanging and sometimes spiking a bit when I engage clutch for shifts and idling high at stop. Why would car run good when warm then start acting up again the next day?? To note I have also noticed a miss at idle but I atribute this to possible bad plug but any info will do..just please don't ask me to reset Idle again or remove TB and EGR to clean cause I already did, and vac is at 20hg at the tree.
