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 notice this when stopped the engine will race and I feel resistance on the brake .
I was told by a mechanic cleaning off the throttle plate fixes the pedal 'sticking'.
