Hello again everyone.
The needle on my speedo does not move smoothly (jerky movements) and both the trip meter and odometer do weird things. Occasionally, the trip meter will jump when it turns over from 9 to 10 miles. Instead of reading 10 miles it'll read 20. Today, on a long run, the odometer rolled over to 40,000 miles. When it got to 40,009 miles it ended up reading 40,510. Any ideas, tips or details of people who can fix it?
