My 89, 302, 4AOD will only stay running while I pump the gas, I changed the fuel filter and am getting a code 22 and 23 any help will greatly be appreciated. The Bronco has been parked since April and when I parked it, it was acting up, shut off occasionally and also hard to start. Right now it will start at first flick of the key but you have to pump the gas to keep it going and will still shut off
