SYMPTOM

The client may "feel" the release of the throttle plate through the accelerator pedal. Some describe it as a "pop" sensation.

This sensation may be felt when:

The client first presses the accelerator pedal after a cold start.
The client attempts to press the accelerator pedal after a quick release of the pedal from wide-open throttle.

PROBABLE CAUSE

Primarily in coastal regions, carbon and salt deposits accumulate on the Molykote(r) in the throttle bore.

CORRECTIVE ACTION

Install a new throttle body and gasket.

NOTE: Cleaning is not sufficient. Changes have been made to the throttle plate angle and stop settings of the new throttle body.
