Need some help. I have an '06 M400 and it never ran right. She stalls when RPM drops quickly as in a tight turn or if I come off the clutch in first. Has anyone had the same experience? The mfg. says it has occured on a number of cars with no definite fix. Any suggestions? Thanks
wasnt an exactly the same post made about a week or so ago? if it wasnt you then there is someone else with exactly the same issue on his M400 so look back over the last few weeks.
