Did it rain recently in your area? Maybe your spark plug boots are old and water got down into the spark plug hole causing a misfire.

Ok guys!!!!! I think its fixed. Pulled another code on cylinder 5. Pulled the coil and put new one in and runs like a champ. I talked to a few people and the plugs that are in here are bosh platinum and they say they are crap. I bought all new motercraft platinum and plan on replacing all of them on saturday. So far so good I will keep this updated if any change. I have been looking all over this forum and it seems like everything comes back to these darn coils. If I could give anyone any advice check all the coils even if you dont get a code.

Good advice. We all have to learn the hard way sometimes, including me. LOL. I learned a ton over the last couple of months troubleshooting mine. Still drive it two footed pulling up to stop lights, because of the problem I was having with the bad coil. Good times.

Chad, Are you pulling the plugs off while listening to the idle to figure out which COP is bad? On mine, I could hear the pitch of the idle change, granted I have after market exhaust.

I did the same thing on mine. It turned out to be the passenger side spark plug foiled out due to an old coolant leak( think it was #1, either way it was the closest to the rad on the pass side.) Hope you find the gremlin.

I've been chasing a similar issue. Just now did I get a code to come up and it says misfire on cylinder 8. It has a new plug and coil pack. Going to try to replace the coil pack connector then fuel injector. If that fails then the only other thing would be intake gasket.
