The oil pressure gauge jumps to the right pinned over the 80 mark.then goes back on 1992 Chevrolet 1500 Pickup

After excelling the needle goes back to normal once a consistent speed is met.

THESE GAUGES ARE ONLY ACCURATE TO LIKE 20% SO IT MIGHT BE OK. CK YOUR OIL PRESSURE WITH A MANUEL GAUGE AND COMPARE. THE GAUGE MIGHT BE GOING BAD
