Hello,

92 W124 Low Power Issues.

I have gone over the all the simpmle and recomended and have hit a wall.
I have done
the turbo wastegate mod
the ALDA function and presence of boost at port
fuel suppy and fuel filters

condition: the car is smoky at all throttle posotions
it starts and idles and revs normally
the power loss was sudden

what else can I check and can the IP timing change irrespective of timing chain position .. that is to say if the timing chain did not stretch is there a condition that could exist with the mechanism of the IP drive sprocket itself or internal parts within the IP that could affect timing of the injection ?

Thank you
