well might be a fuel leak but don't see or smell fuel. fuel cap well that's stock so ya could be that. hose now that's for sure could be it. My fatherinlaw was helping me with the fuel filter replacement this fall when he was here from Maine to visit we could not stop it from cycling gas so he went to see if he could undo the line at the pump. just now remembered that. so will check it change the IAC and replace the cap as soon as i can . got a snow storm coming in tonight. will say it seemed to act up after the whole fuel fiter change thing or replacing the IAC on it. it runs awesome and starts up just fine ones its going. can go down to the store or anywhere and it starts up it needs to sit for along time like over night for it to act this way.
