Once the engine gets warm and you above 15 mph the engine will rev itself while shifting. Once your under 15 mph the engine will return to idle. The more I step into the throttle the more it rev. I was thinking a vacuum leak but it doesn't rev up all the time. The car was in a flood a few years back and everything is original except the IAC
have the same problem?
