| I have a 2000 w/ a 2002 facelift. (beside the point). At about 85000 miles, i had the same thing happen. I was having misfires on the driver side bank as well as the horrible vibrating and of course the check engine light. When restarted, it'd be fine for a while until it went to kick-down when going up a hill. Turned out...my catylitic converters on driver side exhaust were shot (MB recall) and that they had disentegrated into a fine sand, and plugged up the second cat, creating too much backpressure, adn causing the misfire. (there are four cat converters on the damn thing). Sooo check for cracks in your cats and see what they look like. Wait until they are cool and knock on them w/ your hammer (lightly!!) and see what it sounds like. Hallow...trouble. Solid...(Sand buildup) trouble....somewhere in between...ok. Do both sides and go from there....you'll know what i mean. Maybe its not that at all..but thats my experience. |
