help!! throttle control malfunction/power failure/traction control problem

[fourfourto]

-30
Maybe the gas ( water/condensation) froze up and restricted the line or pump

[Hummer eh!]

gas is always a concern up here, but why would the error show up after i was already driving and disappear after i turned it off? in better weather i'd take it for a drive and try a cpl things, but right now if the vehicle fails, i'll freeze my you know whats off.

[Hummer eh!]

earlier today there were 3 separate issues, now it's just down to the throttle control i guess. i will continue my online search. some say i can drive it, others say no because it may go into reduced power mode again and then shut down. guess it's time to call the rental car companies. i'm very interested in finding out the how and why of this problem, time will tell.

Sounds like you had some moisture in your throttle body that froze and TAC motor had trouble moving the throttle. Not sure how to remedy the problem at -30c. That's freakin cold!!

It's under warranty, so take it to the people that "know" - your dealer (once the roads are clear mind you).

Do NOT rent a car.... that's what your dealer is there for - your truck ain't working, they fix it and give you a loaner... probably just a sensor issue - let us know how it goes!
