QUESTION: Okay so I changed my oil Pressure  sending unit but my gauge is still fluctuate while driving and when it gets low the car shuts off oil level is full no leaks. Could it be my oil sensor? ?

Hi there.

Well if the pressure is low when it's hot that would indicate internal engine damage. you need to get a mechanical test guage for this and put it in place of the oil sending unit and drive it and see what the mechanical guage shows. if it is indeed errraic and low there is an issue in the engine, worn out bearings. those engines had issue with camshaft bearings.
