Try changing the air filter ,i had a problem ,at ilde in drive my trailblazer would stall, changed the air filter now it's not stalling and got my power back ,there is a secondary air pump that i have to change ,
not sure were it is ? still not running perfect but it's running better .and my service light is on too.
i got it put on scope ,it's the pump .
not sure if this helps ,but i'm start to run in to problems too,i have a 2004 trailblazer.
i like to do fix things myself ,i hope i can.it's the cost if you know what i mean.

I have a 2002 Chevy Trailblazer. Just replaced

If you unhooked battery it will need to relearn its idle position, should help if you clean throttle blade edge and body of carbon so proper amount of idle air can enter engine.

All warning lights flashing on dash of chevy trailblazer 2003. Runs fine all gagues go dark like truck is turned off but runs fine

All warning lights flashing on dash of my 2002 chevy trailblazer. Runs fine all gagues go dark and turn back on every now and then. Also the gagues all go to the right or stick half way like I am idling at 5000 and going at a speed of 60mph when I am sitting still. I am thinking it has something to do with my computer because the rest of the truck is working just fine.
