Oil Pressure
1997 F150 with the 4.2L. I've noticed that idling in park, the oil pressure "gauge" flickers up and down sometimes. It literally vibrates back and forth. Today, when coming to a stop with the truck in gear at hot idle, the oil pressure gauge dipped far down, prompting the oil light to come on as well. As soon as I put it in park, it popped back up to the midpoint. The engine runs well, but sometimes sputters a bit. I checked the oil level and it is fine. Is this possibly a sender/switch issue, or is something more at play?

Yes, most likely
I would replace the sender and re check the gauge operation
You can put a direct pressure gauge on the engine while the sender is out
That way you can run the engine, get it hot and check the "actual" pressure
Most likely just a indicating or gauge problem
