1994 Cadillac Deville (4.9L). Low Oil Pressure after idling for long period of time. At first the warning came on anytime at stop or short idles. Changed oil pressure signal which seemed to cure the problem. Now it's back after a very long delay in traffic. Checked with manometer and reading 15-13 psi after 5-10 minutes idle at operation temp? No noises from engine, runs smooth. Sound like a clog in screen? Or pressure relief valve? Not sure which way to go.
