I bought e350 with 48,000 miles. Always dealer maintained and serviced no corners cut. When car is first started and driven it seems to kind of stumble or miss slightly until warmed up.It doesn't really run bad its just that its not smooth. I saw where previous owner had complained and had dealer look at the year before. No problems found. It seems if I manually shift the trans keeping engine in 2k to 3k rpm its smooth as butter. Why would it be missing or stumbling slightly when left in full auto shift mode ? I mean this engine at 305hp is awesome, once warm or driven a mile or two its fine for rest of day. I use only 93 octane fuel.any suggestions as the dealer says no problems found.Thanks in advance!!
