I have seen this about a Bizillion times. The cuicuit board on the early Legends would do it, as would a loss of oil pressure. The late Legends, and Vigors with alum. oil pans had huge problems with clogging the pick up screen in the pan and losing oil pressure. I have started to see it on the Integras as well now. What you need to do is get a mech. oil gauge and hook it up where your sender is in the block(kind of a pain) but it tells you weather you have ele. issue or mech. issue. If you run the motor with it flashing and you do have a pressure issue..........find a motor.
If you have any other questions email me bro.
