But check Ebay and other online sites to save money.Īfter completing all the work, my engine was running really rough. I am fortunate enough to have a brother in law who runs a parts distribution warehouse. It would last for a while then the same rough idle and service engine light. In the past, I was replacing a plug coil here and there. I just replaced all coil packs, spark plugs and ICM (Ignition Control Module). P0306, Spark misfires, Ignition Coil Misfires and others. Let Autozone or whomever diagnose the problem for free, beats paying for it!. A burnt valve will cause your P0306 but generally you would notice a constant skip and it wouldnt be random.

Then there is the possibility of having a burnt valve. The response about the vacuum leak although they do experience those leaks, it wont cause that misfire and your code would have been accompanied with a P0171, and or a P0174, lean codes. But more times than not its just that #6 coil. I have seen coils make the vehicles stall out for no reason etc. When a coil emmites a strong enough 'radio signal' from the charge and discharge of the coil, it can make the PCM go crazy and make other cylinders misfire. In other word, your computer or PCM, controlles your coils and everythin else on the engine. Sometimes when a coil goes bad it emittes whats called RFI or radio frequency interference.

although the chances of it are high that it is #6 for your P0306, its not always that way. Ignition Switch Battery Feed (Run and Accessory Circuits)Īssignment of the fuses (pickup and super crew 2000-2001).Well being a Ford/Lincoln tech I think I may be of some help.
