ECU info
Having trouble with my 86 F150 5.0 automatic.
Idles and runs badly when warmed up. Replace CT’s, map, and air intake sensor. No improvement.
Removed ECU to check for bad capacitors. They looked fine. Here are pix of ECU labels. It seems like it is not the original ECU. Truck has been running fine for years with this ECU so that’s not the problem. Anyone know what the last V1A means. Is this ECU for a 1986 F150 5.0. Not sure what the red label means.
