85 ranger 2.3L stalls
My 1985 ranger stall on me a few days ago. Checked fuel filter, plugs and wires, timing, fuel injectors. What I did notice was when I disconnected #1 plug wire eng would die, reconnected #1 and disconnected #2 wire and the same thing happen, but when I disconnected #3 eng stayed running, reconnected #3 and disconnected #4 eng. stayed running. The engine sounds and looks like it has a major vacuum problem. I am unable to detect where it is.
