I have an 87, all I can say is dont mess with the carb! must be cable
positions or something... ANYWAY, I tried to adjust something with idle
fuel mixture on mine, and it affected a couple other things badly, as one
place I probably touch ed the wrong screw, then there were like 8 screws to
adjust mixtures! too much complication on stock carb.
if it is FI, then you are going to need to find others that might have that
motor/experience (2.2 or 2.0 liter engines).
So, there are groups on yahoo still around for these trucks and
Mightyd50.com is down, but there are others. search google for mightymax,
that is the Mitsubishi name (the people who built the trucks and let dodge
put the name dodge d50 on them, which ironically now it is the other way,
with dodge making the Dakota and Mitsu getting to sell them as (something I
cant think of at the moment.). The yahoo group is something like
dodgeram50truckowners, there is another one that is on yahoo we ran for a
while when spamming was bad and the moderator was MIA. The new mod is very
knowledgeable, races and rebuilds the engines in these things, if I recall
Another problem which turned out to be related is the engine temp did
not rise more than the width of a couple of needles from C. I replaced
the rad (had many small leaks), the open thermostat and rad cap and now
the temperature rises and the idle slows down quite a bit. Not as low as
I'd like but significantly better. I guess there's a temp sensor that
leans out the mixture when engine temp gets above a certain point and in
my case it was not. Should improve mileage quite a bit. :-)
