I have an 07 Nitro, I replaced the 6 cylinder ignition coil and it is still reading cylinder 6 misfire. Bought another coil it reads the same....so now we are trying to figure out the vibration it makes as I accelerate up to speeds of 40mph. My engine light is on and the cylinder still reads misfire. We know its more to it than the cylinder 6. Basically my truck is running on 5 cylinders. Did anybody have this problem and how was it fixed
