take it to auto zone or advance since the check engine light is on they can hook it up. may just be o-2 you can unplug o-2 see if it makes it run diffirent?

the autozone couldn't check them ether. I went home and discovered a blown fuse. replaced it the pulled my codes and made the repair. it was a loose plugwire.
