I have a 2000 ranger, 3.0, auto, 170,000 miles. I had the problem with abs, od, and check enginge lights, replaced the abs speed sensor, and everything works fine until I get 65 mph, speedometer starts to wobble and if you increase speed the speedo will cut out and od light comes on and a few minutes later check engine light comes on. What could be the problem now??? It shows no codes, except 01000 because I disconected the battery. I am getting frustrated any help would be appreciated.
