Gas Cap most of the time, wasn't tightned enough...

Do you have the Code number?

Gas tanks are pretty common on the 04 models according to the dealership i get parts from... (warranty of course...)

only thing else on the screen was "Mod $10"

i'm new to the OBD2 thing.. i'd rather use a paperclip to figure out my trouble codes, lol

the PO455 code was in the computer twice though, AZ cleared them out.

DTC P0455 Evaporative Emission (EVAP) System Leak Detected

Tighten your gas cap, if it comes on again, take it to the dealer, you're covered until 75,000 miles LOL.

P0442
is for small evap emissions leaks, the common not tightening your gas cap code.
I could be wrong but I'm guessing there's a lose hose somewhere.

There's a cirucular black thing on the front left of your engine that has a small black tube going into it, I'd check that. Not sure what it is exactly but AFAIK it's emissions related.

edit: just found this,

here's the link for P0442

Both pretty much say the same thing.
