if a this Neural SENSING switch, as you called it, on my fm145 transmission, on my, EEC-IV, 87 ranger 4x4, model STX, 2.9 engine, and is used for, as you said, "to control idle and for fuel management optimizations."
and you said, "Among other things, you may not be able to run some of the self tests (particularly the engine-running test) and your idle will "hunt."
my switch is located on top of my fm145 transmission, just forward of my shifter... so, is that the location for my Neural SENSING switch, as you called it, instead of being just a safety neutral switch, as I thought it was, from what some other people had told me, it was...
is this Neural SENSING switch, as you called it, also, referred to as a vehicle speed sensor switch... anyway, whatever it's called, the wires going to it are broken off, too close to it's base, I think, to solder... so, if it controls the functions of my engine, as you mentioned, "to control idle and for fuel management optimizations."
it may be a good reason my ranger doesn't always run as good, as it should... sometimes, it runs fine, and other times it doesn't... now, that I know that this switch is more important, than I thought it was... I'm gonna try and get it replaced, if I'm not able to solder the wires on, where they're broken off... thanks for your advice...
