What would cause my truck not to idle and I have to pump the gas to keep it running.
I have a 1991 f150 straight 6 cyl It will not idle and dies when I give it gas. I've do a complete tune up on it plugs, wires, cap rotor, module and fuel filter. I've checked idle sensor it seems to be working. Does anyone have any ideals this truckdoes not get drove much about twice a month.
