1991 F150 Starting Problems
I have a 1991 F150 5.0 Ltr engine. I have a problem starting the truck in the morning. I have changed all the plugs, Ignition wires, cap & rotor. I also disassembled the Idle air Control Valve and cleaned it with GUMOUT and still having the same problem. Once running it starts up easy all day long. Any insight would be appreciated.
Thanks
