cylinder misfire help

Might just be a "brain fart" Fords are know to do that. If it comes back on the same cylinder check the spark plug I've read 1 or 2 people on different forums have found loose spark plugs. Matter of fact check them anyway

Nope its the pullies, I was told by Brenspeed that If you dont follow the torque requirements to the tee, that it will throw a code, but the cylinder is not actually misfiring. mine does it every now and then, but I just erase it & keep it moving.

you know, not too sure about this, but I installed the steeda underdrive pulleys on my 05 about 3 weeks ago. The next day I got cylinder 3, and cylinder 5 misfires. I was really worried I had done something wrong with the pulleys,(torqued to factory specs). I went over to a friend's house and asked if he had any ideas. This was one of those things that I felt really stupid about not checking in the first place. We checked my oil and it was really, really low. Put some oil in and I haven't had a misfire since. (also changed my oil the next day) Don't know if this could be your problem too, but mine was obviously just gettin hot, I don't think it had anything to do with the pulleys, just coiencidence. Might just check this

P.s. mine was definately actually misfiring.
