I was suffering the ping ping of a poorly functioning fuel injector. I removed all of the injectors and took them to a shop for testing. One turned out to have a poor spray pattern and release point. While at the shop I noticed some prechambers on the counter - an old one and a new one for another customer's 300 diesel. The parts looked different as I looked through the port at the top. The parts man said that these had been upgraded some years ago, and that I could use them in my G. So, I bought five and installed the upgraded prechambers.
Tonight I finished the reassembly, and after a few minutes of run in shaking and snorting, the engine smoothed back to its normal operation. I took the car for a drive, and I must say, it runs better ever. The power curve and overall operation is much improved.
I do not know why the prechambers were reeniginered by MB, but if that is part of why I have improved operation of my old 300...I like it.
