After having my car on service for oil change, the oil warning light is flashing after driving for awhile when I stop the vehicle in a trafic light or in my house. I reported this problem to the dealer and they have replaced the oil swith twice but the light still on after my long drive to work or home. The service department in the dealer said that the oil pressure is ok and that GM doesn't calibrate the swithiches well.
What is the spec for the oil pressure for this vehicle?
Does the diagnostic for the dealer make sense to you or the oil pump should be replaced?
