Possible misfire under acceleration and idle, no CEL
Drove the M5 first time in a week and 10 minutes into the drive the car began to jerk anytime I started to accelerate. Also noticed a rough idle during a cold start few minutes ago. There is no check engine light and Carly scan came back with no fault codes. Jerkiness doesnít depend on the speed.
Any ideas? Car has 55k miles, so spark plugs are dead? Bad coil pack? Throttle actuators? Car had 1/4 tank of gas...canít imagine gas going bad.
Help is greatly appreciated!
Oh and if it is a coil pack, go with BMW units or do people use something else?
