My first post.
I have a 1987 ranger STX that I am having problems with. I replaced the coil, module on the distributor and the computer but I still have the miss. Ther is no pattern to it that I can see. Its not like a miss but it will be running good and ju8st for a split second it sounds like it shuts off. I bought this truck new in Nov 1987. I have pulled most of my hair (what hair I have) out trying to figure this out Could anyone point me in the right direction, its driving me crazy.
Thanks for any help.

I guess I am not as dumb as I thought. No replies .

Replace the plugs and plug wires.....that should have been the first thing you tried.
