hi I am facing a problem with my merc c220 cdi, the problem is while I drive this happens often that the rpm doesnt cross 3,000 and the speed doesnt cross 130 kms it drops by its self.I switch the car off n start it on again n then problem its okay but when I push the accelerator down fast it moves at a good rpm n speed but it slows down again. Whats the cause of the speed going down and the rpm. When I turn it on n try again I can reach speed of 200km plus but when this problem occurs it doesnt pass 130kms.I have no fault showing on my screen I got it scanned but the scanner shows nothing.

To duplicate these high speed faults you must run the car on a dyno, but I would be thinking fuel starvation as a first place to look.
