2009 X5 35D spuddering
Hello everyone,
I have a 2009 X5 35D with just over 100K miles. It has the EGR delete with the AA Rodriquez down pipe and a stage 2 tune in it. I have had that setup for about 30k and it's been great! Anyway, I started to notice a very slight spudder about mid throttle and would go away if I went full throttle or let off. Now, it's idling rough and almost seems as if it is down a cylinder. I have no codes, no CEL, and no real clue where to begin. Anyone have any suggestions? Thanks for the help!
