I don't know for sure if that's the problem, but I believe this is what happened to me and the Techron solved the problem.
I haven't read much about fuel injectors going bad on the 119 engines. I would ask your mechanic if he did a bleed down check on them first before he started swapping out injectors. The injectors expensive ($200 each). If he gets in there and disturbs the engine wiring harness (most of the wiring harness consists of injector wires), you could end up with more problems than you have now.

I misunderstood. You are saying the coking up could cause intermittent stalling under load when warm . I have been reading so much , I am having a tough time focusing .
Would the white smoke show up 3 times in a row, and not burn off in the initial start ? Its because I am not sure if it was white or grey or a combo of the two, and I have never looked at my start up exhaust before
I also spoke to a MB dealer parts guy , who has his job for 12 years and said the injectors were not particularly problematic in the 119s. He was going to swap them out with used injectors from another car. I am not quite sure if he was borrowing them or what ,as he did not mention money to me at all.
I will tell him to be carefull ,and watch that he be especially carefull when switching injectors if that is what he wants to try next!
I am sorta putting myself in his hands , with suggestions from you guys also to check out by myself if possible , or run by him .
