E46 330ci anyone found a fix for power drop when warmed up ?

[Gammelhagger01]

After surfing the net for a few months, trying to find a fix for the problem I have, it seems to me that a lot of E46 owners have experienced some of the same issues regarding periodic power loss/ dragging feeling when the engine is warmed up.
I was wondering if anybody found a fix ???

I know it can relate to many sources...... fueling or ignition... but I would love to learn if anyone has had the problem and found a fix..... regardles of which fix....

I have done all the usual E46 stuf... From vanos to vacum hoses, DISA, MAF, CCV, TPS ect. Only have I not yet changed the coils, fuel pump or filter.....

NO Fault codes are thrown !!!
