Hi. My 2001 E320 has begun to rough idle when coming to stop. This does not happen all the time, nor does it only occur when cold or hot. Engine temp does not seem to matter. Car behaves as if it is going to go dead (shudders and sputters, lol) and so far, this ONLY happens when coming to a stop or near stop. Just got car out of shop for a/c blower problem, and no codes were mentioned by mechanic. Any ideas? Thanks for your help.

 

Mine does the same thing!! I bought it from a guy that had it pressure washed one day, and ever since then, it started doing that. We still cant figure out what it wrong with it.
