I have a APC Oil Pressure Gauge in my EG and its staying above 100 and not moving at all. I turn the car assc ignition and it moves above 100, i crank the car and the needle bobs down and back to above 100. Is my oil pressure sender unit bad?

Is this from a cold start or has the car been running for a while? Oil pressure is high from a cold start.

Sounds like a bad sender. Mine is 75 or a little over right after startup with a 15-40 oil. After a couple of minutes of idling, you should see it start to go down to around 20-25 at fully warm. See if you can get a new sender and try that.

Yes, bad sender.
