I have an 01 2.4 S/c it's ran fine for the last year or so. Only a couple of times has it had a missfire, so i never worried. Now it keeps popping up cyl 4 missfire and it won't go away. It seems to go away once I hit around 3000rpmsbut I might just not be hearing it. I have already replaced the plugs, boots and springs, coil packs and module, and it's still doing the same thing. Any ideas?

Yes for sure

Check out your plug gap

Did you gap them when you installed or just put them in?
