The tach gauge on my '98GT seems to be "sticking." It works properly above 2K rpms, but below that, it bounces around at random intervals. For example, if traveling at 1500rpms, the tach needle will stick at 15, then jump to 17 and back to 1K. Other times, it will completely flat line. :mad: Generally, I can bump the top of the dash and the gauge will go back to normal, but it still isn't smooth operation. What could be wrong, and can it be fixed without replacing the gauge? Thanks in advance!
