ok, did another test drive, better now that the heater hose for the MFI thermostat is hooked up, but same problems eventually... I did some reading on the tank ventilation system, and neither hose in my engine bay was hooked up at all...
Looking at the diagrams here...

in that first diagram from Grady lines 5 and 6 were disconnected.... I can tell which is which because only one is long enough to be #5, but I can't tell where #6 "Purging line from activated charcoal container to engine air cleaner" hooks my air filter... so thats my next question/research...
