Type "oil pressure:gafiero.org" into a google search bar.
This will search just the gafiero.org website. Should bring it up

Possible causes of oil gauge jumping:
Bad wiring to gauge
Bad oil sender
Wet oil sender (specifically, V6).
The only post regarding wiring that I can recall is the one about changing the old type oil sender to the newer type (88 Fiero type).

If you want to do a test to determine if it's in your circuit or in your engine, I have a mechanical gauge that you can attach in place of the oil pressure sending unit.  I have used it several times, clamped to the vent grill so I can look back at it while driving to determine if my sending unit or gauge is faulty.

Thanks for your inputs.  But I found what I was thinking about, it was the pegging of the oil needle when you start.  Will try what Fierofool  said.  Thanks again.

I believe the following works:

Does the sender still connect?  This reads like an either/or.
