Have a problem with surging RPM's when in neutral. Its not throwing any codes, I checked for intake leaks, cleaned the MAS, the IAC, TB, adjusted the TPS correctly (I believe, .96 volts at closed closed throttle), and reset the computer.
It only happens under a certain set of conditions.
Engine is not under load. Vehicle is moving (if I am at a complete stop or just crawling to a stop the issue goes away), and the transmission (5 speed) is in neutral. Only does this when the engine is at operating temp. If it is cold and put it in neutral and coast it kicks down once, then goes back up to cold idle rpm.
Any ideas guys?
Thanks
