go to the local parts store: autozone, napa etc. and have them read the code then you can diagnose it.

Agree almost completely, I'd suggest buying one. They're not too expensive and the convenience of having one is so worth it.

But certainly get the code checked before trying to fix anything Guapo. Without knowing what's really wrong you're just throwing parts a problem hoping that they'll fix it.

sometimes it's the simple stuff. Tighten your gas cap 3 clicks, disconnect the battery for 30 minutes, reconnect, and see if the code comes back.

If it does, follow the advice above. These stores will read the codes for free.
