I have been experiencing a serious loss of power when the engine is hot, to the point where it is dangerous to drive.. Not an issue I had in the past. I have the SID display on so I can check that the IOFF is way high (-150 to -200) even when the intake temperature (Tair) is still pretty low ie 40C; those two items can be seen in SID display mode 7 (#5 and 6).
Most of the sensors are new, the DIC is from 2007 (I tried another one too) , the TD04 turbo has roughly 15K , I tried 2 Air Mass sensors and I can't find any pressure loss in the whole intake (tested per WIS procuedre).
Any idea as to what could be wrong: fuel system, other, has anyone run into the same issue (I remember a post pointing to the brake booster but I don't seem to have an issue braking; I can't get the logic of the b.booster being responsible for power loss only when the engine is hot)
I'd really appreciate any help because as I said, it is quite dangerous to drive due to the super slow acceleration.
Thx
