the check engine light you are getting sounds like and electrical problem, have the battery and the alternator tested, and have autozone or the like pull the codes off for you and see if you can figure out what they are....

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.

You have some kind of ECU problem. You will need to hook to the diagnostic port to find the problem. Your vehicle has gone into limp mode. This enables the vehicle to run, but at a diminished level until you can seek help for the problem. Do not continue to drive it this way as you may cause damage to the engine depending on the nature of the problem.

It's fuel related, check your fuel filter to see if it's clogged, let me know. Good luck, Jim

best bet is to stop in at a Pep Boys, Autozone, or similar big autoparts seller, and ask for free trouble code scan, which should pinpoint area causing problem. If not obvious by codes, what is necessary to repair the problem code, get back to us with those codes and we will be glad to assist you further. Better this way, takes away the guess work, and saves you money, as well as getting it right the first time.
