oil pressure gauge going up and down when car gets warm saying stop engine check gauges it has oil in it changed sending unit and it still doing it.
Hello it would be my pleasure to assist you. You'll need to take it to a shop that does more in depth repairs than Firestone is capable of. They will need to remove the sending unit and check pressure with a gauge to determine if it's an internal engine problem (bearings or oil pump) or if it's an electrical problem with the wiring or instrument cluster.
