Hi, could anyone please help me identify the problem with my SRT6 that I am trying to solve for more than one year?

It actually does three things that may or may not be associated.

1.) From time to time when accelerating (even during light acceleration) it shuts down the engine for just a second. I guess it disengages the supercharger.

2.) Again, from time to time when I go slowly it goes to the limp mode. (It again probably disengages the supercharger and I must say I really hate those vibrations it does). Sometimes it takes 3 restarts of the engine to get rid of it.

3.) It does strange sounds that go from the needswings cai in idle. I found out that that the throttlebody plate (I mean that plate inside the throttle body) is somewhat loose and hits the body of throttle body and this sound is being transfered to the cai.

Over that year I have tried a lot of things. As it does not write any codes most of the repair shops and merc stealerships told me I am making it up (It simply does not do it during their short test drive) and those who encountered the issues were clueless. I changed the ic pump as the first thing, did not help. I thought It might be map sensor -> did not help. I am constantly loging all the sensors together with my wideband o2. The first problem is visible as a sudeen drop in air pressure and wb o2 shows similar af as if I released the gas (checked fuel pressure and it is ok).

I must say I am starting to be hopeless.

Thanks for any help
