hi group i have a 91 yj w/ I6 and the following probs:
the needle in the water temp gauge sometimes would for no apparent reason jump to the far right (highest reading) as far as it can go and stay there -- light tapping of my finger against the gauge brings the needle where it should be -- near the middle of the scale
the oil pressure gauge has the same problem except that no amount of tapping on the gauge would bring the needle to where it should be -- showing variations in oil pressure. the needle stays at highest reading at all times.
what's wrong? can someone help? many thanks!
