When I take my foot off the gas pedal, the RPMs are not dropping as they used to. The engine eventually returns to idle, but it takes way a few seconds and I'm using the brakes more than I'm accustomed to. The check engine light has not come on and I disconnected the battery in hopes that the ECU needed to re-learn something... no change.

Any suggestions?

 

Going to try the Idle Relearn Procedure tomorrow ... we'll see

 

Dang, no change.

Any suggestions before I take it to the shop?

 

Clean your throttle body

 

Yeah, I tried that too. Also tried disconnecting the battery again.
