But soon as I let off the gas, it then dies on me. And it want start again unless I hold the gas pedal to the floor and then it starts wide open.I change the fuel filter and it still dont want to stay running unless I hold the pedal to the floor running wide open. Its a 1992 isuzu pickup truck with fuel injectors. Can you help me with this problem
