Ok, 2002 X5 3.01 M54 engine.
I replaced the valve cover yesterday. Since I was already there, replaced the plugs as well, I used the Bosch +4, funny thing, those were the old ones as well.
After replacing the plugs, she started funny, I got a check engine light, I ran the codes and it says multiple misfires.
I was wondering if those Bosch +4 need to be gapped? I dont know how that can be done.
Any thoughts?
