I have a M45 03 and have known about the emission codes for a year or more but now I am getting the #2 cylinder misfire... I have swapped out coils and plug from another cylinder and cleared code and it comes back to #2 misfire, I did a compression check and have 150psi. I am not sure where to go from here. Can anyone help

You might have a wiring issue if another coilpack is also failing in the same spot. I don't know the 03's much, perhaps EdBwoy can chime in? How does the spark plug look? Any oil or anything like that?
