Intermittent deceleration pop, EVAP low purge flow, sensor stuck rich Bank2 sensor 2?

I've had the car for two years now rebuilt transmission just got done with cylinder head work, car runs like a dream except since I had gotten the car, I've gotten numerous DTCs periodically, for b1 b2 running lean large leak detected evap, small leak detected, evap low purge flow. I have new 02 sensors, all new fuel system only thing I haven't messed with or replaced would it be the charcoal canister? I'm at my wits end I've done compression tests and leak down tests everything is in good order given the mileage I do value my car though and do my best to learn whatever I can and do what needs to be done to make her run efficiently and enjoyable but this small problem I can't seem to get a bearing on I hope someone may share some insight on the matter. I also have screen shots of my live data from obd2. If there's any way, I could upload it for review I'm still a novice when it comes to full interpretation of everything. Thank you for your time.
