Hi there, I have a 1997 E320 with 3 error codes coming up in conjunction with my Check Engine Electronics light. I don't have the actual error codes with me but the descriptions were 1. MAF defect 2. air intake temperature defect 3. cylinder 2 misfire. I purchased a new MAF from alloemautoparts.com and replaced that so assuming it's the right part the MAF should be fixed. (I haven't had the codes read again since replacing the MAF). So my question for anyone out there is: can anyone help me understand what errors 2. and 3. above are and how to look for a fix. The original problem was that the car was idling poorly, stuttering, etc, which is what I would expect with a bad MAF. However, after replacing the MAF the car is still idling poorly and the CEL came back on... Any ideas? FYI, the mechanic who originally read the codes said that a new set of spark plugs may be all that I need for the cyl 2 misfire. But I'm curious to know if anyone thinks that errors 2 and 3 above could cause the car to act like when the MAF goes bad...

Check to see if water has gotten into the cylinder that is mis-firing. I had that problem with a 97 C280 after someone had "washed" the engine. Also check for bad plugs/wires/etc with the ignition system. If its a bad spark plug, that could indicate a bad cylinder, i.e. not combusting properly, fouling out the plug.

Good luck..
