Did you ever get your issue fixed?
Too anyone else planning on cleaning their TB. Be sure you ONLY use a quality [U]Throttle Body Cleaner. [U][U]Best to remove the TB to perform the cleaning. Be careful not to get cleaning into the electronic portion of the TB. Always a good idea to reset the throttle positioner after the cleaning is done.
Turn the key on (do not start car). Slowly press the gas pedal all the way to floor, then slowly release it. Turn key back to off and you now have reset the yhrottle positioner.
