get yourself down to autozone and have them pull the code for you and see what is wrong

Autozone will pull the codes for free, but before you buy anything there, post the code number here and we can help you with the repair. Sometimes AZ will try to sell you something you don't need (EGR valves come to mind...).

I've had god luck with AZ reading codes for me, never tried to sell me anything, maybe because the one near me is always really busy, lots of volunteer customers. I've also used their "loan a tool" service a few times, that comes in handy too.

the one by me sold a guy $300.00 worth of o2 sensors cause that was the code they pulled, guess what, it didn't fix the problem and the light was still on.

the truck comes to me (yes i am a professional) and i CHARGE the guy the standerd diag fee to find the problem. it was just a 5 dollar vacuum elbow!

good luck with autozone!!!!

Yeah just b/c the code may read o2 sensor its usually another part that made that o2 sensor throw out a code, anyone correct me if im wrong, but an o2 sensor "smells" what is going on in the exhaust system, as for how much or not enough fuel is being burned. If the exhaust fumes are not what the o2 sensor thinks they should be it will turn that check engine light on. Look for other defective parts that may have made one of the o2 sensors go bad.
