I have an 02 e320 wagon, I will give all the details I know when this problem abruptly happened. I was gunning it around a corner in the rain, I had my plastic cover off from changing the oil, at high revs just before it was going to shift it hiccuped like the over rev sensor cut in, just a few 100 feet after that when I gave it throttle it acted like it was out of gas. If I backed of the peddle it would catch again for a minute and then either have a huge loss of power or act like it was out of gas again. It has consistently done this for about 3 days now, once even hiccuped again and went into limp mode with the "BAS/ESP" light coming on, so I had to pull over and turn the car off and restart it and it was back to the same erratic problem, that light went out. Never a check engine light through all of this though. Any advise would be greatly appreciated. Thanks, John
