I had my purge valve unplugged for a few days and it ran great, but i couldn't put in more than 0.25 gallons of gas in before the pump shuts off.... then after plugging it back in still went to the gas station 2 times with the same result. Finally this afternoon it let me fill it up. Its running fine still so far, but i did pick up p2097 and p2099 codes.... i did see misfire on cylinder 2 a couple times previously. i might pull and replace those 2 plugs... I ruled out the coils and wires as i swapped them from the other bank when doing the intake.
