Rough idling and stalling sometime

Check the hose between the inletmanifold and the pipe to the brakeservo it normally gets old and a crack in so the engine sucks false air on cylinder 4, causing engine to run rough or uneven.

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.

All those codes mean a specific cylinder missfire. Start with tune up. Plugs, wires & air & fuel filters.
