Due to the snow that we had over the past few days my 100 meter driveway is a mess even after being "cleared out". My turn around area is a solid three feet of snow and I have not even attemped to tackle it. Fortunately almost directly arcoss the turn around on the other side of the driveway is a clear spot in the yard that I am using as a temporary turn around.

Anyhow, as a result I turned my E300 around this morning and backed it into the garage for my wife. I did not pay any attention to it running as it seemed to run fine while turning it around which took about three minutes. After I backed it into the garage I left it running just to see how it ran. After listening I now suspect the fuel even more. It ran without a miss for a while then there was a very faint miss. Then fine then another miss. After the second miss I let it run about thirty more seconds and no more misses. The lack of a pattern leads me towards the fuel.
