The VGT solenoid can fail. The VGT solenoid receives signals from
the engine control module to adjust the boost that the (variable
geometry) turbo is generating. A defective solenoid can also create an
overboost or underboost condition when driving.

Have problems with truck increasing idle while at a stop light. Truck also had a loss of power, and finally would not accelerate while pressing the gas pedal. I took it to a ford dealer and they said it was the VGT, so I had it repaired. Truck was running fine for about a week and then it left me stranded on the 91 Fwy in the fast lane... it was the same issue, loss of power. Almost feels as if the truck is getting choked out?...
