The Info Center on this 2004 Colorado z71 4x4 says "FUEL CAP" but I replaced the fuel cap twice, that did not help. The truck smells like rotten eggs.It has NO CODES. Could it be the EVAP purge Valve/control solenoid?

    it says that because it has a gross air leak. you need a shop to do the real diag with a smoke machine, scan tool and a voltmeter. then, they can tell you the failure and give you a bid.
