I was traveling on a divided highway and approaching a slow moving truck in the right lane ahead of me. There was another truck behind me in my lane. I moved to the left lane to pass the slow truck. Just after I began the pass my pickup slowed quickly and began flashing error messages: stability control disabled, engine power reduced & service stabilitrak. The truck behind me had moved up close and followed me around the slow moving truck. I was unable to accelerate and continued slowing quickly. I had just enough room to swerve in behind the slow truck as my speed fell below its speed. The truck behind me narrowly avoided a rear impact with my truck, which, I believe, would have been catastrophic. I pulled to the right and tried to speed up. About 40 mph was all my truck would do. I stopped and got out the manual. It said to reset the stabilitrak, turn the vehicle off for 30 seconds. I did that and the truck seemed to functioned normally, at least as far as engine power. I still had traction control & stabilitrak error messages and the service engine light was on. I was able to return 40 miles to my home town with no further incidents. I was able to get my truck into the chevy dealer on the 30th. The service rep recognized my description immediately as a "throttle sensor" failure. It was repaired under warranty. There have been no further incidents. My concerns are dual: first, only luck and years of emergency vehicle operation training enabled me to avoid being hit from behind by the following truck when my truck unexpectedly and without warning lost power. An impact would have likely be life threatening considering the speed and proximity of two trucks. Second, subsequently, I have found multiple internet reports of this issue going back several model years and my service paper work indicates a gm service bulletin for it exists.

Every time the weather is bad, mainly rain, the service engine soon light flashes, and the truck jumps. Sometimes fuel injector cleaner will help, and 2 times the distributor has been damaged. The incident date was the first time the distributor went out, and stranded me in the middle of an intersection, no accidents thankfully. The second time was April 20,2003 after warranty on the first was over.
