Trouble Code p0304

My service engine light illuminated on my 1996 chevy lumina. The OBD is giving the code P0304.

Does anyone know, what that means what that code means.?

You have a misfire in cyl 4.... advice... get a Haynes Manual for your car (available at just about any auto parts store) it will help u diagnose the problem tell u the codes and best course of action.... BTW I had a misfire in #2 ....replaced the plug and then had the code cleared...no prob since...Good Luck :smile:

Thank You. I appreciate your help. I will take the car to my mechanic and have him tune-up the entire car.


Thank You Again
