Question

Why is the service engine soon light still on after i replace the coil P0301 and 1 spark plug?

Answer 1

Hi there,

This could be caused by a bad fuel injector, some sort of intake gasket leak or a leaking cylinder head. Also, if something is wrong inside the engine you will get this code as well.

thank you, this helps a lot, if there is a leak in one of the cylinders would that not give me another code?
