The light engine soon is on since few months. The code inside the PCM is RANDOM MISSFIRED. IT's not only 1 plug that is misfirrging.
I change the plugs and put a new set of wires ffrom ford on the car and still misfirred? WHY?
I would like to know where i could start to search to resolve the problem?
Thank you.
