2000 Ford Focus Q&A
2000 Ford Focus Question: Can this code cause major engine damage over time?
Well, i recently replaced my valve cover gasket in the vehicle and when the shop put the cover back on they didn't put on the wires correctly which is what i think caused the code to be thrown and stored in the history. Im going to clear the code and see if it happenes again because after they plugged in the wires correctly the vehicle ran fine. Felt like it did before they messed with it. So, my question stands if it is a misfire in cylinder four can that cause major engine damage over time? - DrizzleDizzle
YES ALWAYS. DID YOU HAVE CODE PO304? CLEAR CODE AND SEE IF IT COMES BACK. P.S. FIND A NEW MECH IF THEY SHIPPED A CAR RUNNING BAD - globalhelper
