P0353 Ford - escape 2002

Question

My 2002 ford escape 3.0 is throwing a P0353. I changed all coils and had a new pcm programmed into the vehicle. Car is still pinging and has no power. My only conclusion would be wiring? I ordered new pigtails for all coil over plugs. Am I on the right track?

Hi there,

It is possible there is a wiring issue, however I would also check the compression on #3 and might try swapping the fuel injector for #3 with the one next to it. If the misfire moves with the fuel injector then you know the injector is the problem and not the wiring.
