help with oil light/ fuel gauge

[thirty_too]

this is what she is doing.... first of all she runs just great, all fluids including oil are right on. the oil light comes on when it is warming up between 148-172 F and cuts off and doesnt come back on. Again, i checked the oil and it is right on. Second, im running at two bars on the fuel gauge and then it starts blinking like im on reserve and i know for a fact that i have more than reserve inside the tank. This has happened the last two times the tank has gotten to two bars. any ideas? maybe they are related? let me know what you all think about this.. thanks in advance

Maybe a bad ground, try unplugging anything that goes to the instrument cluster acouple of times, just a thought.

For the fuel guage check the connectors underneath the tank.
The oil level sensor is inside the oil pan, but the oil light seems to be a universal "check engine" light also. So it could mean anything.
Do you get any error codes in diagnostic mode?
