Have a code po446 on a GMC Sierra -evap vent system problem as per dealer did the vent solenoid update then the canister and purge valve. Spent enough to get a waiver (Do not want that) but could not get one without a fail paper. Well it will fail with the check engine light on. After repairs and clearing the code and driving 90+ miles monitor readiness still not ready, then bam on comes the light again, same code. I think without emmision testing there would be much less pollutants in the air. Just think about how many cars sit and idle at the test stations and the crap we go through to get ready for retest. Then think about drive through everything, Shut off the car and get off your fat ass and walk into the place. So sorry to vent but if you can help with the code I'll shut up Dan HM1011
