Our 2002 Chevrolet trailblazer loses power and the trouble lights flash including the service light and reduced power light come on. I have changed the 02 sensor, flushed the transmission, replaced spark plugs and had the emission system checked all to no avail. Our mechanic cannot isolate the problem and all things we have tried has failed. We have reset the computer several times to no avail. This is a problem and safety issue. We have had no help from GM.

2002 Chevy trailblazer service engine soon light will come on along with the reduced engine power light and the vehicle will not go faster than 40 mph. Sometimes it will not go more than 20 and 10 mph. I've taken the vehicle to the dealer and they cleaned the throttle and changed some filters and 2 days later....the same lights come on and the engine power is reduced. The dealer doesn't know what the problem is so the vehicle continues to do this and has been doing this for the past 6 months. There was a recall on the control arms in 2001 that affected the 2002 Chevy trailblazer. I purchased my trailblazer in 2002 so I didn't receive any recall information. My control arms need to be replaced and I want to know why my vehicle isn't covered under the recall.
