So my speedometer all of a sudden is going crazy and can go above 2000 Rpms or governor kicks in speedo says I'm going 80 out of my drive way and over 100 mph at 30 mph. Speed sensor removed and governor doesn't kick in any more but still no speedo. So replaced speed sensor, checked transmission gear, and reprogrammed computer still doing the same thing. Has anyone had this problem before and know how or any suggestions. It's an 03 rubicon thanks
