my check engine light came on in my 96 s14 with a ka24de. i diagnosed the problem and it gave me the obd code P0446. Apparently, its the "Evaporative Emission Control System Vent Control Circuit Malfunction". I checked all the hoses and everything and none seem to split or anything. Maybe a bad gas cap? Im not sure, just tryna see if anyone else has had this problem before and fixed it. let me know

Maybe start with the easy stuff...you did check all vacuum lines. I would also make sure you don't have a leak on the intake side. Could be the gas cap, evap canister, CV solenoid?
