Q: Car dies when gas pedal pressed

asked by on

Car will idle, but when given gas, it will die.

Your symptoms have many potential causes. When you press the accelerator, the engine is under load and sucking in more air. The engine control module (ECM) should respond by providing the engine with more fuel. If the vehicle hesitates or dies under acceleration, usually there is a problem with the air/fuel mixture. The underlying cause could be anything from a vacuum leak to a failed fuel pump. I suggest you have a trained professional, such as one from YourMechanic, diagnose your car’s stalling issue so that the appropriate repairs can be made.
