Yeah thats why I took it into the shop was to test my oil pressure to make sure it was just something in the gauge. And not just having a bad engine.

Restating my earlier post...
Since you've verified that engine oil pressure is good, perhaps your auto shop has a universal "electrical" tester that you can use to actually "test" the dash gauge and sending unit, to help you determine whether the low pressure reading on the dash gauge is a faulty sending unit, a faulty gauge, or wiring/connection problem.  Look at the image for an example...

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!

25 PSI at idle is not unusual for a stock engine.

The "low" idle pressure I experienced in the above thread was due to anti-cavitation grooves machined into the pump cover.

sorry bd I thought you were talking about a universal gauge to test the oil pressure itself. I have already replaced the sending unit so I think its safe to say its in the wireing to the gauge or the gauge itself. And I will try to ask the shop tomorrow if they have one.
