SOURCE: sluggish acceleration traction light comes on

this must be a 2.3 miller cycle. it is going into "limp home" mode. when this happens, it wont rev over about 3k, and tcs off/tcs lites come on. it feels a lot like fuel cut. probably the check engine lite is also on, and what codes are stored? most common is P1525/26 and 1540, which are the solenoids that control the abv. the abv controls boost, and when this valve is not working proplerly, the pcm stops communication with tcm, and it goes limp home. if you can locate the solenoids, they are on the back of the engine, right next to the egr valve. from right to left, you need to look at the second and forth. you need to ohm them when they are hot. normal is around 26. if they are over 30, or 0, they are bad. there are other possibilities, but this is most common

SOURCE: i have an 06 gmc denali and the traction active

most likely a wheel speed sensor(abs sensor)has gone bad or it is not making a proper connection. you need to take it to a repair shop that has the proper diagnostic tool for it so that they can tell you which one of the four sensors is defective. hope this helps

I have a 2006 GMC Envoy Denali, when I am driving especially in the snow or slick roads. My stabilitrack kicks off and I have no power in my gas pedal. Then I let it sit for a bit and it goes off, but as...

I doubt very much it is the accelerator pedal which is basically just a potentiometer to feed go faster/go slower information to the brain. These things tend to either work or not and don't usually play hide-and-seek.

On those vehicles equipped with anti-lock brakes the same sensor information can be used for an electronic stability control system to improve traction in poor conditions by detecting which wheel has lost traction and applying the brake on that wheel. If the system cannot cope the engine power output will be cut until traction is restored.

It would seem the system has a fault and should be checked out by someone familiar with that type of magic.
