Tachometer irratic
Just over the last day or so, the tachometer vin my B-13 has started to fluctuate wildly. it still works, BUT it will fly up way out of proportion to the actual engine speed. Then, after driving for a while it will settle down and seems to function accurately. Is there a sensor that goes bad ? What could cause this ? I did search, but could not locate anything related to this problem.
