assuming there is no abnormal noise (knocking or rattling), and this happens independent of engine rpm, and you are inferring this from the gauge reading, it sounds like either 1. bad sending unit (common) 2. faulty wiring (common) 3. bad gauge (least likely judging by your description)

What would cause the oil pressure to drop to zero seconds after the engine starts and then after driving less than a 100 yards the pressure goes back to normal your ride is a 2000 F150 4.2?
I, like many other people, am having the same issue. Come to find out - it's a faulty oil pressure relief valve. The valves get stuck in the open position, allowing the pressure to read normal while driving or reving, but losing pressure when stopped at idle.
Do you have to worry about not having enough back pressure if you want to remove your muffler on your 2000 Dodge Neon?
Yes a lack of back pressure can cause the oxygen sensors to read improperly, which would turn the check engine light on.
Is an oil gauge supposed to go up when you accelerate and back down at idle?
Found out this can be cause by a faulty oil pressure switch best known as oil pressure sending unit
Where is the oil pressure sender on a 2000 gm sierra?
the oil pressure sender on a 2000 gmc is in the back of the eng. top side

blood pressure goes back to normal
Where is the oil pressure switch on a 2000 Corvette?
It is on the back of the motor under the intake.
How does lowering back pressure affect the efficiency of the car?
Having a lower back end will cause your vehicle to tilt up in the front, causing drag. so lower back pressure will cause loss in Fuel efficiency.
Can being on the computer cause pressure in the back of your head?
no but in can cause severe headaches like migraines
Why would the oil gauge on a 2000 Navigator jump from normal to 0 and back to normal repeatedly?
Because that's the way it is.
Where is the oil pressure sensor on a 2000 F150 4x4 and why would the gauge go to zero then suddenly shoot back up to normal range?
its on the left side of the motor..you get to it through the wheel well..i change alot of them
How do you stop a horse from pulling back?
Get a naughty halter that has pressure points and when they pull back the pressure points dig into there head and they wont want to pull back,cause they know it hurts them.
What is the problem when the oil gauge on a 2000 Astro fluctuates as you accelerate and decelerate?
How much does it fluctuate? It is normal for oil pressure to rise maybe 20 pounds when you rev the engine. My SUV goes from 40 pounds to 60 pounds and then back down to 40 at idle. this is normal. The faster the engine rotates the more oil pressure is needed to keep everything lubricated properly.
