Due to a change from mechanical to electronic parts in automotive vehicles since 2005, the drive-by-wire system has been installed in virtually all vehicles. Thexton offers the Infinite Adjustment Throttle Depressor, No. 592, utilizes a telescoping feature to adjust the tool up to 3’ in length. Once the tool has been adjusted to fit the steering wheel and the pedal, the user can rotate the knob located at the top of the tool to make the most finite adjustments to get engine RPM levels at the desired setting. This tool works well for adjusting the RPM level for tune-ups, cylinder balance tests and A/C work.
