Cylinder misfire '98 F150 4.2L
One more question guys:
I have been pulling a code for a little over 1 year now thats showing a Cylinder #2 misfire. I don't notice the miss, so its not missing hard. I pulled the plugs, regapped them, then replaced them, with no change. Then I pulled the wires and tested them, and replaced them to be safe. No change. Then I replaced the Coil Pack just to be sure, and no change. Anyone have any clues as to what else might be causing this? The only other thing I think it could be is a clogged injector in that one cylinder. Thoughts? Thanks for the advice.

I know this is a late post but here's something for someone in need that is reading this . My 98 4.2 liter was experiencing the same problems described in this forum. Misfire on cylinder 4 replaced plugs wires coil pack the whole nine. After a long trial and error I removed my valve cover to find a bad rocker arm. The pushrod was lodge inside the rocker arm. You would think there would have been a lot of noise coming from the motor but there was actually only a slight ticking sound. Not saying its your issue but it is something to think about.

It still seems to run good, but its definitely something for me to check.
