Misfires are always such a pain in the a** due to the detective work required to troubleshoot. Seems like a million things could be the issue, and the codes you get either tell you too little or send you in the wrong direction.

In addition to the issues above, other forum members with misfires have reported the following:

Bad or dirty MAF
Melted CATs
Bad exhaust gaskets (usually header)
Hole in intake plenum
Failing O2 sensors
Failing Crankshaft Position Sensor
Failing Camshaft Position Sensor
Failing fuel pump
Dirty fuel filter

Good luck! Keep us posted.
