I all, my engine management light has turned on on 2005 c class c230k, when idle the revs are going low and sounds like its going to cut out. From other posts I have seen this could be air maf, so took apart and gave it a clean, but no good it still runs badly. If I disconnect the connector from the air maf sensor it runs perfectly again. Is there anything else it could be? But makes since that disconnecting the air maf makes it run fine.
Help please
