Hi
I have an 05 durmax that has a low power issue off the line and to about 50-60 km an hour. It had 1 bad injector and now the balance rates are +/- 2 from 0 at idle in park. It consistantly has code P0101 and when accelerating has black smoke and is slow to accelerate, when it gets to the 50-60 kmh it then wakes up and sets you back in the seat and the smoke clears. Any thoughts would be great.

Have you checked your airfilter? Lots of smoke and no power means your not getting enough air into the engine

P0101; Mass Air Flow (MAF) Sensor Performance

First things first, make sure the connector that plugs into the MAF is on tight. If thats not it, pick up a can of MAF cleaner and give it a good cleaning. If that doesnt work, your going to have to bite the bullet and replace it. Good luck.
