Question about 2004 Volkswagen Jetta
Every week or two my car will go from runnning fine to stalling at an idle. I have to press the gas peddle to floor to get a start. When it does start an EPC light and battery light comes on and the car runs rough. It will run rough for a couple of days then just fine the next. What is the EPC light? How do I fix this headache of a car...
EPC= electronic pedal control it is a sensor and is located in front of the brake pedal . Depress brake with one hand ,the sensor with the other and release fast. this should disengauge the EPC lock listen for a thunk made by the EPC lock disengaging.
Go to auto zone. They will use a code reader to help you find exact component or components having errors. If its not the EPC.
it sounds like your mass air sensor or the throttle control sensor may be bad. Your gas and air may not be mixing properly thus causing your car to sputter, hesitate, and idle rough. It could be some other thinks like a bad plug or wire etc. Good Luck hope this helps. Please rate me if this helps thank you.
