Misfire Cyl 2

well its not that simple, the car gave me this code about 4-6k miles ago, so I changed the plugs code did not come back until a few weeks ago. so last weekend I figured I'd swap the cols from cly 1 and cly 2 to see if this cured the problem or if the code would move to cyl 1 (making it a coil pack problem) and the plug looked good, well it did not still reading cyl 2 misfire what should I check next

Check if your coolant is dropping, you might have a cracked head gasket and leaking in cylinder 2.

I'm sure you meant P0302 Cylinder 2 Misfire Detected .

Try something for me, I know it's far fetch but try pushing down on all relays and fuses in the underhood fuse block. Some people have had luck in solving hard transmission shift this way.

Maybe the even injector fuse needs removing and reinstalling due to dirty contacts. Diminished contact conductivity would reduce voltage available for injector coil. I know it is pulling at straws but you never know. Everything else seems to fail for you. But I suspect a bad ground.

Found this diagram that shows where Injector ground and transmission module ground connect "coincidence" maybe. Maybe it's loose.
