i cleaned out the tps sensor yesterday cause it wasnt changiung thru gears like it should (that problem is solved) but now i cant get the revs back down to the way it suppose to idel and when ur accelerating and take ur foot of the pedal it just suddenly drops so much so u feel the car ***** forward when the revs brake i cant figure out what is causing it , is it possible the timing is out or do i need to reset the ecu somehow , i idid try and jump the ecu into diagnostics etc but it worked for the revs on idle for 1` run then went back up to sitting around 1500rpm its driving me nuts
