88 F150 Intermittent Issues
1988 5.0L, EFI, AOD.
Water pump, smog pump, power steering pump, alternator, battery, ac compressor, distributor, spark plugs, wires, cap, rotor, dizzy, ignition module, ignition coil, vacuum lines, injectors, high pressure fuel pump, in tank fuel pump of front tank, have all been replaced in the last 2 years. Put on a GT40 upper and lower back during January, fabbed up the trans cable mount.
Pretty much have had this issue since day one of the GT40 swap. Truck idles around 500-600rpm when its warm, runs rich at an idle, but if I advance timing any more I get detonation and it becomes way too lean under load. Lately it's began slightly hesitating or stuttering off pedal, randomly, and normally happens when it's warm.
Also, Is it important fuel regulator gets its own vacuum line?
