I have an 06 duramax. I bought the vehicle 2 weeks ago. Yesterday leaving work, my pickup barley wanted to leave the parking lot. When you get on the throttle(normally driving acceleration), it is extremely sluggish and puts out a white smoke. If you continue to give it more throttle the smoke turns to black and puts out about as much smoke as a pulling truck does. (The truck is stock to the best of my knowledge.) The black smoke continues for a while and then the turbo finally lights and the smoke clears up and the pickup starts to gain speed.
I pulled the codes off of it today and found these:
p0101 MAF sensor performance
p0102 MAF sensor circuit low voltage
p0402 EGR flow excessive
p0299 turbo underboost
Since I had 2 MAF sensor codes, I borrowed a buddies sensor and put it on my pickup. I still had the same trouble. We put mine on his and his worked fine. So I don't think that it is the MAF sensor.
I tried to back it out of the parking spot today to show what it was doing yesterday Any throttle makes the engine run extremely rough and it actually killed the engine a couple of times with it still in park.
Does anyone have any recommendations for me to try?
Many thanks.
