will the chip from a 97 torus3.0 fit a97 ranger
can I replace the computer chip from a car to a ranger . will it help with
th gas milage? I am getting 13 mpg now. also I keep getting a code for
the 2--4 cylinders missing. I have replaced the plugs and wires.
the compresion is all even. The why is the milage so bad?
