Understanding Car Idling Issues

The problem can be either with the engine, the transmission, or the computer system that controls your car.

Causes of car idling issues can range from a clogged air filter to a faulty fuel pump. If your car won’t stay running unless your foot is on the gas, it could indicate a malfunctioning idle control valve. Other potential causes of car idling issues include vacuum leaks, dirty fuel injectors, and a malfunctioning transmission.

It is important to have car idling issues diagnosed and addressed promptly to avoid more expensive problems down the road.
