I have a bad miss and I fixed it by new cp and now it's doing it again so I bought a hole new set changed them out and still have the miss can't figure it out any help
I had almost the same thing #3 had a misfire around 2300rpm but at idle it was fine put in a new coil pack and the problem was fine. Maybe your Mass air meter is cracked or there's a leak in the induction system could cause the motor to run ritch and in a result a miss fire or bad spark plugs just an assumption based off experience.
