I have been reading up on the forum for "misfires" and there are several which have a problem around 100mph doing (3000-3500rpm) and that is just when I encounter my problem. I think I'm going to take the car to the dealership to see if the car med any error codes, and have them disconnect the ECU and put all the wires back to see if there is problem there (bad connections). The more I read about the problem I'm starting to believe it is faulty sensor somewhere, the question is which, normally I don't do over 80mph and never encounter any problems.


Found this for example on the MB forum "The problem wasn't a misfire, turns out the transmission ECU was sending signals to the torque converter instructing it to lock" or " faulty 02 sensor was causing cyl 1, 3, 4 to misfire, weird. Didn't think it could do that".

Thanks !!
