E90/E91/E92/E93 (2006 - 2013)
for the past few months my car lost its power and i been trying to find where the issue is.
[2008 e93 with jb4, DCI]
* got a misfire in cyl 6 = changed spark plug and swap coil places = misfire did not move, it continued on cyl 6.
* also had rough idle so i figured had to be my injectors...
