04 lincoln Aviator misfire #8
hello guys i really ran into a wall with this car and would like to get a second opinion about this issue.
it keeps giving me the CEL code of "misfire #8" I've checked the coil and spark plug by removing them and putting them in the #5 piston and the code persist misfire #8. There is no oil on the plugs so valve cover gaskets are fine. Wen I first saw this code I was sure it was going to be a bad coil but now I don't know. The misfire occurs wen its at idle speeds around 600 rpms. I've also replaced the cam sensor sense it was one of the original codes.

It could also be an injector, a bad valve, a bad spark plug, or worse, a bad cylinder/piston. See my thread here....I went through the same steps, ended up my piston is jacked up.
Kinda intermixed in this thread. http://www.lincolnsofdistinction.org...t=31485&page=2 Coils http://www.lincolnsofdistinction.org...ad.php?t=32167

Tomorrow I will test the compression and the injector should be coming in.
What's the compression on this motor?

Did you erase the p0308 after you switched?

Sounds like an injector. It could also be an intake leak also... I would do the compression test first, and also try a leakdown. Make sure you go WOT on the compression test.

Anything above 140-150 is sufficient. Make sure you swap the coil, boot, AND plug to the different cylinders. You can also swap injectors very easily without replacing parts. I've never had a bad injector throw a check engine code FYI.
Question: Is this a dead miss (ALWAYS misses) or is it intermittent like mine? If its a dead miss it could also be a bad wire, a chipped crank shaft pickup or something more "mechanical" vs electrical.

+1 on what J says. Also, does the engine light flash at you sometimes?

Flashing means it's misfiring right NOW.
