Throttle Body Replacement

Common symptoms

Throttle body and electronic throttle body issues can result in the engine stalling, failing to start, warning lights on the instrument cluster, and hesitation or power surging on acceleration.

Common misdiagnoses

The throttle position sensor is often blamed for throttle body issues, and care should be taken with electronic throttle bodies to ensure the accelerator pedal is not the faulty component.
