Speedometer
Here are my problems on my 2000 F-250 5.4L. Every so often, my speedometer and odometer doesnt work for the first 10 minutes of my drive. Afterwards it comes back. Also, when it isnt working, my overdrive indicator keeps blinking. Anyone have an idea what is wrong?Another problem: My Check the Engine light is on. After reading the owners manuel, they said to fill up your tank with "good" gas three times. After three tanks of use, if the light is still on, they recommend to take it to the shop. I put some zMax fuel treatment in the tank and i will see what the outcome is. Hopefully it was a little water in the tank!
Thanks for any help in advance
