Folks:
I have a Dakota '89, 3.8l, 4spd/4x4, with a dead computer,
ECM 4379.927. This part is no longer available through the
dealers or apparently anywhere else.
Help -- I am dead in the water so to speak - truck stalls/dies randomly, and
often will not restart for many minutes or longer. It's a great truck, but a
bit unreliable now.
Many thanks, Jim
