Misfiring of Cylinder No. 6
I have a strange problem with my M5 - where it recently giving me an reduced power message where the RPM redline goes all the way into the 4.5 & the car losses power big time and start rattling.
My problem it sometime it does this and sometimes it works fine, but mostly of the time it is giving me a reduced power message.
On the computer it showing misfiring on cylinder 6 -- all the time, when the reduce engine appear misfiring on cylinder 6 error comes up on the computer.
I replaced the plugs, and change the coils, cleaned and changed couple of the injectors but the same problems is still happening
