I used to have a M102 engine in my 190, that engine drove me crazy with its idle/throttle issues. Even a German shop I took it too couldn't get it running right, most likely was a worn fuel distributor + other issues.

End solution? Swapped it with an OM601 diesel. Car became 100% reliable for the 5.5+ years I drove it after that....not to mention 35% better mpg. Only drawback was having 50 less horsepower.

Interestingly enough my M116 v8 was perfectly reliable for the 55,000+ miles and 7+ years I had it after I replaced all the rubber boots/grommets/hoses on the engine to stop vacuum leaks. And it had the same type of fuel system. (CIS-E)
