p0442 code Changed gas cap a couple of years ago, what else should I look for? It might be bad again? Also, how do you clear the code? Disconnect the battery? For how long? I did this for about 5 minutes and light is still on.
Got a local Autozone? Tell them to scan it, and when they say "Change your gas cap" tell them you already did and ask if they can erase the code to see if that was the fix.
They should. There's a chance they might not, but worth a shot IMO.

H. Uncle.
its an evap code. possibly a fuel cap, purge valve, charcoal canister, lines, etc etc.. i just sent my pcm off to madz28 and had all the emissions tuned out. worked like a charm
Just changed the purge valve on the wifes car. Tried a new gas cap first. It started having starting problems after filling up. Didn't matter how much gas was in the tank, it did the same thing. The valve was sticking open and allowing fuel to pass through.
