1999 Olds Intrigue, 3.8 eng.Last month, I replaced the Oil Level sensor while changing the oil, which was causing an oil leak due to a broke seal. Three weeks later, the "Low Oil" light came on and stayed on shortly after starting the car. I checked the oil level and it was full. I went ahead and drove it to work. No engine operating errors during the drive. While continuing to drive the car (yes, driving it), I did notice that the light stays off after starting the engine at operating temps, but comes on while the engine is cool (Faulty sensor?) I asked an Autozone associate about a Oil Pressure gauge to test the engine but was told that they dont sell such a thing. Chiltons repair manual says to use a 3amp fuse jumper to test the Oil Level and Oil Pressure sensor. I have no idea what a fuse jumper is.
