Well I had good intentions of taking the car out and snapping a few photos, but about midway to the park, my oil pressure gauge dropped to "L".
After a quick investigation, I discovered the wire had worked it's way loose from the sending unit. I replaced it and headed home. Somewhere during the ride I lost it again. I popped the hood, and this time the wire was out of the spade connector. I cleaned it up, put a new female spade connector on it and got the gauge to work again.
Pretty scary but in the end...just a loose wire.
