I just recently purchased a cherry looking 1995 MB C220 but with a couple of mechanical issues that i took care of myself. After purchase I replaced the throttle actuator, maf, fuel filter, pump and hose. Replaced all vacuum hoses, changed oil and slapped on a set of new tires. Now I'm not getting any trouble codes now but before I had a maf TC and a knock sensor TC. Main reason I replaced the the TA and maf was that I was told that the old parts were causing a condition that prevented speeds over 70 mph. Well still has the problem, it will not climb above 70 mph. Has anyone had this problem?

what does the car do after 70mph? cut off, lack of power, misfire?
wow thats different, :surrender: never heard of that before, and same this was happening before the throttle body work? i hope someone can help with this.
When I saw you said rpm's go up but no speed different I thought of the time my clutch went out, same thing happened and on the higher gears. Maybe it's the last gears not engaging properly or slipping. I'm not a mechanic just a thought. Have you done any tune ups? Plugs, trans fluid, etc?
The plugs were done by previous owner right before I bought it. Engine is smooth, transmission shifts smooth and quiet. Upon wide open throttle from a standstill the engine and transmission propel the car quite well until 70 mph were it just will not go beyond that speed. Like a speed limiter of sorts. I'm guessing the cars computer must be setting a limiter due to some sensor or signal from something that may be off or not functioning.
