so my check engine lite came on in my 2000 blazer, so i had auto zone scan the codes
1) knock sensor, i knew it was gonna throw this code i have a 2001 engine in my 2000 knock sensor not tapped in the block yet.
2) p0410- secondary air injection system
3)p0300-random cylinder misfire
4)p0135-heated oxygen sensor bank 1 sensor 1

More specifically:
P0135 - HO2S Heater Circuit Bank 1 Sensor 1
P030x - Random/Multiple Cylinder Misfire Detected
P0410 - Secondary Air Injection System
Also, you may want to run a search for each individual code as they have been discussed before.
