Well check engine light came on and I was just wondering if anyone would know anything about the problem. Went to autozone and it read as fuel trim on bank 2. So seince there are so many variables I went to a local shop and they hooked it up. When it was reading the O2 sensor readouts it was not rolling 800 to 100 it was stopping at numbers and it is something with the fuel managment. Could it be a Mass air flow sensor? Well im not to sure what it is but when I out some STP injector cleaner in the light went off. So would it be dirty injectors? Well I was just wondering if there were any problems like this that anyone has had befor

 

Either o2 or your MAF went bad Mercedes diagnostic would be more specific.

 

what yr and how many MILES on your E55?

 

..............as obove plus one or two cylinders misfiring.

well got my injectors flushed out and cleaned today and the problems gone I didnt think it was an o2 sensor because now it is reading fine and it is a 00 with around 52k miles

 

9/10, it's the MAF.

 

well light came back on today so im gunna take it tommorow to get the new sensor lol hopefully it fixes the problem

 

Good luck, keep us posted.

 

yup that fixed it

 

What fixed it?

 

Probably the MAF.

I had the same problem on my 55. Fixed it. Well, the new MAF did.
