My ram revs up when I put it in park
#13
since IAC is replaced,and the idle settles down on a throttle/gas pedal tap, i'd guess that either the TB plates are binding open, or the throttle cable is binding open, or the TPS is not sensing the idle position right.
if you remove the air cleaner and sit up in the engine bay, can you repeat the problem and eyeball whats going on, and compare it to how it looks after you bump the throttle.
