    My truck was stalling and shutting off at stop signs or red lights. I had the throttle body clean and had no more issues.

    Ours will say traction control off, stabilitrack off, and then say reducing engine power. It also can not sit and warm up or it will die. We have been waiting on a new throttle body for over two weeks.

    My 2009 suburban behaved the same way, rand rough, stabilitrak light, traction control light, service engine - the whole 9 yards, this all happened at 0500 hours on the way to work. My husband got it to the dealership and they indicated it was the throttle body, we will see when it is picked up...not very happy about any of this, what a dangerous situation...
