Carbon deposits on the throttle body may cause any of the following issues: Idle speed fluctuation, incorrect idle speed, difficulty accelerating way from a stop, and or increased accelerator pedal resistance. Our technicians tell us a revised throttle body and associated parts are available to resolve this issue.

I was told by a mechanic cleaning off the throttle plate fixes the pedal 'sticking'.

The RPM revved up to 5000 - cannot stop even if I press the brakes, very hard. Have not fixed it yet, don't know if it is the throttle body (I cleaned it already) or the piece next to it. Alex (973) 951-5385
