I've got a '97 C230 with a CEL, codes p0170 (fuel trim bank 1) and p0300,301,302 (misfires on cyl 1,2).

I did a search before posting, found one saying the air mass meter is the likely culprit.

I replaced my AMM the other day, with a used one that came from a misdiagnosed MB elsewhere. The light came back yesterday.

Is there another way to diagnose the problem? Values I can observe with a code reader? (self adaptation, O2 sensor values, etc)

Thanks,
