I have a 2003 Chevy trailblazer,when I accelarate my service engine soon light came then the reduce engine light comes on; suddenly my truck slows down. Shut the engine down, start it back, the lights go off and my trailblazer is back to normal until it happens again. Does anyone have a solution before I get costly repairs? HELP!!!

Get the engine codes pulled. Once you have them it will help track down the issue. Not really much you can do otherwise unless you want to throw money at it.

If the service engine soon light is flashing, it means the computer has detected an engine misfire with the potential of catalytic convertor failure. Don't just tune it up. Bring it somewhere they can read the trouble code. Sometimes it will designate which cylinder is having the problem.
You need to get the fault codes read to determine where the problem is that set the SES light. Autozone will scan your car at no charge. At some point you will need to get a mechanic involved to further diagnose the codes.
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.
