About a month ago I was getting a P0302 Cylinder 2 Misfire, I changed the spark plugs, coil pack and intake manifold gaskets. After all that it still threw a P0302 but I was getting way more power than I had in a while. I did some research and found two other suggestions, 1.) Replace the Battery because the ECM can be sensitive to throughing codes when the battery is low, I bought my nitro on an ebay auction and the battery was old and 2.) I found a youtube link about a 3.7 L Jeep liberty still through a code after the basic changes you have done, the mechanic said it really was really a rough idol and not a true misfire problem, if you don't drive the car at highway speed for a long enough period carbon can build up on the intake valves, It was recommended to drive the car like you stole it, basically I took it on the highway for about an hour ride and would floor it from around 50 MPH at 2K RPM up to 80 MPH at 5500 RPM, once the transmission shifted and brought it back to 2K RPM I would let the car slow down to 50 MPH and repeat the process.
I can't say which of the two worked but I did both and have had no problem for over a month now. If that didn't work I was going to do the CRC intake valve cleaner but ended up not needing to. Try number 2 and see how it goes. G
