evap problem
I have an 06 LS2. I installed a m112 supercharger a few years ago. I have been getting a code P0455 and a GAS CAP on DIC warning. I have replaced it twice but still have same issue. Is there something in the vacuum lines or a valve that could have gone bad. Car runs great but have a problem with CT emission.
Thanks

Need to smoke test the fuel system to locate the leak. Possible purge solnoid stuck on or leaking, Vent valve leaking, Or even a fuel leak somewhere on the tank/lines.

Not going to be a fuel leak. Most likely a vacuum leak in the system. Could be a purge/vent solenoid not quite seating, or a bad o-ring at a connection, or even a kinked line, or a pinhole in a line.
Has this been an issue ever since the blower went on, or something that has just popped up?
