Question

I replaced sensor will start but run rough if you push gas peddle it will stall

Answer 1

Hi there,

I would check the timing belt to start with. Also, this could be caused by an issue with the mass air flow sensor, so try unplugging it and then start the car and see if it will run better. Make sure to check the wiring harness for the crank sensor as well. Sometimes the wiring pushes out of the harness at the connector and causes this problem.
