Default Miss fire after new head?
Just put a new head on a 2000 Cherokee and now it's running rough? New plugs, head, gaskets? Everything is plugged in.. It's second head I've done( other on a different jeep) and it didn't do this.. Any ideas??? Thanks

Hard to say, so many possibilities. Any chance of borrowing a code reader?

Also, was the head brand new, reman, used?

Clear the codes, swap that coil pack, then scan it again. Is the misfire following the coil pack, or is it still on #5?
