I've got about 105,000 miles on my 2004 E. Several times in the past week the Check Engine Light has come on. When it does, the engine won't go above 3000 RPM. When it hits 3000, it stumbles badly, as if the engine will shut down. It did it to me today while going down the highway at 70 mph. Turning the engine off and restarting seems to take care of the problem, but the light does stay on for a while.
Any ideas what could cause this?

Any ideas what could cause this?

Lot's of ideas, but instead of guessing, why not make sure the oil level is full and then go have the code scanned and you'll then have a much better starting point towards a diagnosis?

Had the same problem

Yeah I have an 03 ex with about 112000 and I had the same problem I found that when I tightened the gas cap down really tight it stopped after a day or two and the light turned off .... Has something to do with the pressure in the gas tank.... Easiest thing to do would be get a new gas cap... I've been meaning to but haven't got around to it but haven't had the problem since I tightened the cap down as tight as I possibly could
