And always remember what ZIP said - Autozone, Advance Auto, O'Reilly's - they all read codes for free. Advance even printed my codes out for me - but that was not good enough, I went out and bought an Ultra-gauge so I could read them myself.

In any event, if you see the light, stop by a store and get the damn code(s) read. Then come here, we can take it from there.

(And there are a lot of codes that really are nothing to worry about - sure you want it fixed eventually, but many codes are NOT a big deal - it's all part of the clean air acts.)
