P1665 GM EVAP Vent Valve Solenoid Control Circuit
P1676 GM EVAP Canister Purge Solenoid Control CKT

as a note, this vehicle has a bad battery. I plan on replacing it tonight. Not sure if that could possibly be related.

I've got two o2 sensor codes which I've had forever. I've now got the two top codes related to the evap.

car won't start unless i spray some sort of flammable spray into the air system. Then it runs just fine. I don't know where to start. I've hear an ignition system is a common cause of this which would suck because I just replaced the ignition lock cylinder. should have replaced the whole thing. LOL.

I've also heard that if the EVAP is having problems it can blow gaskets, foul plugs etc. It also says something about vacuum leaks but I would think the car would show that when running. It runs fine. Just won't start without spray. And I wouldn't think the ignition would be this either but I obviously don't know much.
