Was driving 2nite in pretty jammed hwy, then accelerated to 6k on 1st then 2nd and then my beast started to misfire, lose power and Service engine soon light came out. Car was running like a **** for a next 20 min. then parked it, turned off the engine and after a minute start it again. No SES light no misfire. All cylinders were alive.
Maybe ignition coils got hot coz was driving for 4 hrs???
Just bought my M, does she have COP or one coil for 2 cyl
?? Do they brake often?
