      I finally got my codes read at autozone and I got code P0443. I know it's something related to the evap. system but other than that I can't seem to find out much more. Any one know what part(s) need to be checked/replaced?

      I'm not where I have access to my ODB-II materials but from memory, it's a gross leak - meaning a leak equal to a .060 hole in the system...check all your fittings and the cap....when I am where I can check out the book on it I'll see if a) My memory is any good and b) what you can do.

      EDIT. Ok I am stupid. It is NOT a gross leak but a purge valve circuit error. The purge valve is near the power steering pump as I recall... check your wiring, but in all liklihood for once a code MAY actually point to a bad component. It will have 2 hoses coming off of it, one goes to the charcoal cannister.... Not sure how you would test it.... but I am guessing that barring any obvious wire issues, it is the valve itself.... sorry for the earlier bad info. I left it up so you know I am just like all of us... and make mistakes too - a LOT !

      It refers to your EVAP system/Emissions. Try cleaning your IAC.. I've heard that replacing the PCM can also correct it but I wouldn't go that route unless it was a definate. Not sure if it would be related to your 02 sensors or not.

      I had a feeling it was the charcoal canister, I'll check it out today and hopefully that'll get rid of my check engine light and fix the super crappy gas mileage im getting.
