hey everybody i have a 07 f-150 w/the 5.4lt i have been getting p0452 and p0461 trouble codes. know what the book definition for these codes are but what can i do to fix them because when i pull out into traffic or am pulling a trailer and get into the gas the truck will stall out if i lift off the gas fast enough the engine will keep running if i dont the engine will shut off. it will start right back up after this and i can get going again. if i really lightly get into the gas i am fine but it takes forever to get up to speed doing it that way. also the fuel gauge works when it wants to if i wiggle the wires( i have dropped the tank to inspect the wires and everything was good) on top of the tank it will work for about 5 mins and then go back to empty and every now and then i will work just fine. the truck has sat for the past year in storage while i was gone and started maybe once a month. it ran fine for about the first month but the next two month i have been having these problems. any help would be really helpful. thank you all for your time.
