Can someone comment/confirm my systoms & diagnosis?
Driving home from work tonight I stopped for gas, A max fuel fill up (low range). Getting back on the highway all of a sudden I noticed I was doing 85, but it didn't feel like 85, and people were passing me. At the next light I was stopped and the speedo bottomed out at 15 MPH (not 0 mph). So as we rolled back to highway speeds the 70 mph became 85 and so on... I confirmed this with my GPS.
When I got home I turn her off and waited a minute and then restarted. Now the speedo jerked around some and then landed on 50 mph. Two more times with the same erratic movements, and I'm doing 140 in park. The speedo does not go successfully go through its min to max to min power on test.
Is this the servo problem? Or did I glitch a computer cal table somehow?
Do I need to do a system reset via battery disconnect??
Thanks in advance...
