Default Running Rough

I have a 2003 Chevy Trailblazer that is skipping & sputtering. I had the plugs & plug wires changed and it is now worse! Any suggestions?

Test the coil? Check the injectors any, pull any codes?

open the throttle body butterfly so you can see if there is a bunch of carbon build up in the throttle body and on the butterfly

Have it scanned for trouble codes. Is the CEL flashing?
