My 1998 Explorer V-8 AWD has a code of P0442 - Evaporative Emission Control System Leak Detected (Small Leak). I tried changing the gas cap but still get the same code. From what I'ved read, it could be a tiny pin hole in a line or the canister is failing. Where is the evaporator canister located? If the hole could be that small, how can it be located? Any other ideas to what the problem is?
Thanks. Rob
