Pontiac Repair: Oil Pressure Sensor, oil pressure gauge, rally sport

Question
My oil pressure gauge freaks out! It's buried at about 5000 psi! LOL.  How difficult is it to replace the the sensor/relay and where the heck is it?! 1991 Buick Regal 3.8 liter. Rally Sport Model.

Answer
Hi Bourke:

It's pretty easy to replace. It's loacted right by the oil filter. on the back side of the engine facing the fire wall. You do need a special socket to remove and replace it though. It just threads into the engine timing cover and has 1 electrical connector on it. Good luck :)
