    2002 WRX CEL P0442 Issue

    Hows it going, new to the forum and looking for help. I had some work done by my mechanic and now I'm having a CEL pop on every 100 miles or so. 01/02 codes both are P0442 Evap Leak Small Leak. I had a new coolant lines put on, i had an aftermarket intercooler put on and then taken off with stock going back on, and catback exhaust. Other than that I'm keeping it as stock/OEM as possible at this point (don't need any issues cars plenty fast, i use it for a all purpose vehicle : Snow and surf). I appreciate any insight to what I can do to elevate the issue.
    1) new gas cap?
    2) replace charcoal canister?
    3) no clue hahah

    P0442 code

    Did you resolve the P0442 code? What happens to the Evap canister? Does it crack? I have a 2002 RS with a P0442 code. The Autozone cap didn't fix the code. I have ordered a Subaru cap. I have been unable to find any vacuum hose problems in the engine compartment. The filler neck has some rust, but doesn't appear to be leaking, at least it's not wet on the outside.
