1st Generation Toyota 4Runners (84-89)
I made a post in the other Toyota forum #56 and I have since found the problem to be a faulty wire in the fuel pump wire harness under the passenger seat.
The truck I have is a SR5 1987 4x4 2.4L 8 valve 5 speed. It has a new problem now, the truck runs ok and then it shuts off as the engine light comes on. I am in the process of changing the air flow sensor and hope that this is the problem. The truck has 205,000 km.
Are there any of you who have had to change air flow sensors?
What kind of mileage are you getting with these old trucks. I am getting only about 13 mpg highway, I am not sure if this is normal or low because of the problem described above.
