Turbo "fart" while accelerating and no power

[jamesb23]

Got in my truck to run a few errands today and drove about a mile when it started farting and smoking black while I was accelerating. Also it has almost zero power and I had to limp home at 20 mph. The farting noise is the exact same as when it goes back through the intake when you let off to quickly. I replaced the egr about 2000 miles ago but just to be sure I pulled it back out to check if it was stuck and its fine. The turbo was replaced around 20,000 miles ago last January. I need to get this thing fixed ASAP as it is my only vehicle.

Just a guess, but I had similar problems and it turned out that the turbo vanes were sticking. Had to remove the turbo, take it apart, clean it, and then reassemble and reinstall.

check ur intercooler boots

checked all pipes and connections..no leaks, disconnected the vgt wires and nothing changed same with egr disconnected nothing changed. I unhooked the batteries for like half an hour and let it idle then drove it and it still runs like shi*. I'm leaning towards the turbo vanes stuck but its hard to believe they would do that in 20,000 miles when its run hard everyday. Anymore Ideas as to what this could be? I really don't want to go to the dealership but need it running by this weekend.

Are you able to check for codes? If so, what codes are you getting? Do you have access to a scan tool that can monitor live data? If you do, you need to look at your MAP, BARO and EBP readings. Compare what the three readings are at key-on/engine-off to start.

I got a scan tool and watched everything while I drove around and oddly it started running totally different and making zero boost. So I checked the codes and it had 2 that were turbocharger related and ALLDATA said to test vgt voltage and function. The voltage was ok so I put 12 volts right to the solenoid and the vgt was functioning. Long story short plugged it back in cleared the codes and the truck runs flawless I guess if it happens again i will just get a pig tail and vgt solenoid and replace them. Thanks for the input guys this site is great.
