I just bought a Chevy S-10 1999 4 Cylinder 2.2 Engine, but I can't pass smog, it gets REJECTED due to 3 OBD sensors: OBD Catalyst, OBD EVAP, and OXY SNSR, it says in additional information NOT COMPLETED, can anybody give me more information, I have driven it at least 200 miles since the first time they came up, any idea, bad sensors or what but please let me know thank you in advance for your help.

 

Disconnect the battery overnight...drive to the test facility....They'll do a tailpipe test instead...and you'll pass
