Question type: Maintenance & Repair

Holds steady pressure when cold, as soon as it warms up or after a long drive. The oil pressure gauge starts jumping around shaking. etc. at idle when stopped at a light. When in park the gauge acts normally.

How is the engine running, any noises, oil level fine? Then it might just be that the oil pressure sending unit is dirty or faulty.

My money is on a worn sending unit. Being erratic then returning to a normal position when cold or while at idle leads me in that direction. I do not believe there is a pressure problem because you did not mention any symptoms of oil starvation. There are two types of guages used and I do not know which one your vehicle has. There is a mechanical type which works off of springs which get worn and electrical ones. On the electrical guages mesaures very tiny differences in resistance to display a reading. Dirt and corrosion can affect both. Sending units are cheap enough, and it is the easiest to replace.

If it not the sending unit. do this next. Remove the sending unit and attach an oil pressure guage in its place. You will probably need a reducer to match the size of the guage fitting to the port. Use a mechanical guage, not an electronic gage. If the guage reads steady and does not fluxuate, the the problem is probably in the dash guage. If the pressure fluxuates, then obviously the problem is before the sending unit. If you are interested, you will have to look up what the proper reading should be for your particular engine year.
