My 89 4.0 is up for CA smog in Feb.
Passed well 2 years ago.
Have been getting a steady 19-20mpg mostly highway 70+mph.
Question is: Does Good fuel consumption indicate an efficiently running mill?
Also does anyone know how to check the HEO2 signal, not just the heater element curcuit?:wow:
thanks fellas
