I'm afraid I may have an issue with my new motor. When beyond half throttle, I get a code for random misfires and specific codes for misfires on cylinders 1, 3, and 4.
I have cleared the codes multiple times but eventually, when beyond half throttle, I receive the same error codes… random misfire and misfires on cylinders 1, 3, and 4.
The new motor did have new plugs and coils installed and now has 9,200 miles. Any suggestions or ideas would be appreciated before I change the plugs and move the coils?
I have been looking but have not found similar scenarios on other F10 M5s. Is a code typically seen when the HPFP is failing?
