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

Is a flooded car so it may be a module causing problem try cleaning throttle plate on both sides an diac hole with choke cleaner. Check for a vacuum leak.

I didn't think of the throttle body. I found a throttle position sensor for 24 bucks so I ordered that just in case. I checks for a vacuum leak but could find anything obvious. I did find a wet spot on the Intake gasket.
