Re: 04 Envoy - state Inspection Fail
Welcome to AF, the evap system may not test/come online with under a 1/4 tank or over 3/4 tank. In NYS 2 monitors can be offline and still pass. It just may take more driving for everything to reset, no other way.

Re: 04 Envoy - state Inspection Fail
It will take 4-5 drive cycles of complete cooldown to cycle the system . Just got an 08 and they put on cruise and they disconnected the battery and it had the same issue . 4-5 drive cycles where it completely cools down and it should pass emmissions barring any mechanical issue.
