the gas tank pressurizing seems to be that you have the vent solenoids or purge valves's vaccum lines hooked up wrong or one of them simply not working....double check all your vacuum lines per TSRM vacum diagrams..
Improperly routed vacuum lines also seems to be the problem with the vehicle idleing and stalling when removing the oil filler cap...
as for the smoke or usage of oil during acceleration after a downhill is a symptom of bad valve seals.....
