Misfire repeat on cyl 6

hazkirby · 04-07-2018, 02:13 PM

Hi guys.

about a month ago I had a misfire on cylinder 6 on my n52.

I swapped coils with cylinder 2 and then the error moved to cylinder 2 also. Thus I bought a new coil and stuck it in cylinder 2.

Car was then off the road for 2 weeks due to an oil leak from rocker cover.

After this I used it two days last week, then on Thurs I had a rough engine again. Checked codes and it was cylinder 6 again. So I bought another coil pack but this time no difference.

Any thoughts on root cause ?

Spark plug?

Spark plug or injector issues.
