Hey, I'm new here, have a little problem I can't solve. I have an '87 Ranger which started idling rough and is really down on power. i changed the cap, rotor, wires and plugs, as they were all REALLY old.... no change. Next step is to check for codes, right? So I get my scan tool, open the hood and look for the connectors. I found the big one on the passenger side, between the air cleaner and the fender, but the single pin STI (self test in) is nowhere to be found. Isn't it supposed to be in that same harness?
I'm kind of stuck until I can trigger the test sequence, unless I want to keep throwing parts at it, which i don't. Anyone have a wiring diagram that would tell me what color the wire is that I'm looking for?
Thanks
