Default oil pressure gauge flipping out

My oil pressure gauge started doing this today.


I've seen it twitch a few times before right after getting of the interstate but just a few jumps and it stopped. Today after driving for about 45 minutes on the highway it did this consistently at idle. As you can see it stops when I give it a little bit of gas. Any ideas what's causing this? I would think that it's a sensor of some kind.

Mine does the same thing... also after I get off the interstate. It goes back to its normal position if I shift into neutral though.

I have a 98 Ranger 3.0l and it is doing the same thing. I changed the sending unit and no change. I believe I am gong to have to change the pump next. The motor is running very bad which never has until the gauge started acting up so I hope changeing the pump will take care of everything. WE WILL JUST HAVE TO SEE!

Update... my guage now flips out whenever I'm at a low RPM or idle. I'm going to change my oil tomorrow and see if that has any effect. If not, I'll start looking at the pump.

Probably a bad battery. My speedo jumped at idle real bad after I had to jump start my truck.

Mine did this too. Turned out my cam sync sensor was bad and I didn't realize it till it killed the motor one day
