All show, no go. That's how your fuel-injected car would act once its throttle body conks out. On most cars, the throttle is mechanical. A mechanical throttle uses a cable to make the throttle linkages move the throttle plate. The plate's position determines how much air flows into your car's engine. There are electronic throttles as well. Electronic throttle systems are controlled by the engine control unit (ECU), eliminating the use for a throttle cable. The ECU sets the throttle plate's position according to information sent by different sensors (such as the engine speed sensor and the accelerator pedal position sensor). Both types of throttle bodies, however, become prone to failure as time passes. Once the throttle fails, your car may idle or accelerate roughly. It may not even start up properly at all. Simply put, throttle failure can paralyze your car. The throttle body may become defective due to corrosion, leading to stuck parts or burnt-out sensors. If you want to keep your car moving, make sure it has a fully functioning throttle. Auto Parts Deal has just the right stuff to help you with that.
