My X is surging....what I mean is I'll be driving and my engine will surge from 3 to 4k RPM's and then go back to 3k.....it happens whether I'm driving 40 or 80mph.

I just had the adaptive values re-set recently (9/7) and it did it 2/3 times again during a trip today. Not sure what to do now other than bring it back again and ask the dealer to re-flash the DME & EGS modules.

Any thoughts?
