#2 of 12 Re: 2007 Impala LTZ "starting disabled service throttle" "engine power reduced" [lauriebrown]

I've been having the same issue with my car I have a 2009 Impala LT, and starting the beginning of January 12" the sensors to "service traction control" and "engine power is reduced" have been coming on. I've been to 3 different shops including Chevy who told me that it had something to do with the brakes and a hub and low pressure cap, they charged me 1500.00 for all that. The sensors were still coming on. I went to another mechanic before who told me that I needed a new computer chip in my car and I had a voltage problem somewhere and a small leak. One day the indication to tighten my gas cap came on and all the sensors went off after that. Easter Sunday, the sensors came back on and went away again and now after just getting the car fixed again last Monday the sensors came back on, however this is the only time the car hasn't displayed the "starting disabled service throttle" message and shutoff on me. The dealer has told me I'm not under warranty anymore and I only have a power-train warranty but I was told there is nothing wrong with the electrical system, transmission or engine. No one seems to know what is wrong with my car either, including Chevrolet. I was told I had too many miles on there for me to file a suit because I feel the car is a lemon. Considering the fact that I purchased it in November of 2010. I'm looking for suggestions also, I live in Baltimore County, MD.

i just started having the same "service throttle" "engine power reduced" issue. I have been looking online and surprised on how many people are having the very same issue. I will need to get my car fixed asap and do not want to go thru the same money spending spree trying to figure out the problem. Has this been figured out? Can you give me some info on what is causing this so i can get it fixed the first time?
