I have a 2004 Chevy Trailblazer that I just bought a few months ago. I have 75k miles on it. Tonight I got in my TB and drove no more than a mile and my acceleration went to nothing. It would only idle. The Reduced Engine Power Light and SES came on. I pulled over and turned off the engine and restarted it. The Reduced Engine Power Light did not come on immediately but after I put it in drive it did and I lost power again. I have read a lot of post here but haven't found a concrete solution, but all the post are several years old. Has anyone found a definite solution to this problem?
