I just brought yesterday a 08 ml63 with a 125000 on it. When I Walmart today. I floored it and it started running rough. I didn’t drive that hard coming from the dealer. I scanned it and I got a bunch of codes and some greyed out codes. So many im not sure where to start. I haven’t even owned the truck 24 hours yet. Any ideas?
The standard diagnostic approach using DAS is to read all codes and record or take photo of codes, then erase all codes and drive the vehicle, then retest and see what codes reappear.
In DAS, the codes show up as CURRENT (F), CURRENT and STORED (F), or STORED (f).
So I reset the codes and repeated what I did yesterday. I did drive it lightly for a while with no issues other than a slight miss. I had no issues until I pushed it from a stop. If I was moving and I pushed it it didn’t seem to have any issues.
