I GOT A 1998 SILVERADO 4X4 ENGINE LIGHT ON CODE P0446
Well code 446 is for a problem with the EVAP system which vents fumes from the gas tank to the vapor canister.
You would need to check the system using a test chart for that code.
You can look online for the test procedure and the equipment required.
