CAN ANYONE TELL ME WHAT THE OIL PRESSURE SPEC IS AT IDLE FOR A 1997 PONTIAC SUNFIRE 2.2 4 CYLINDER?

I HAVE 6 PSI AT IDLE AFTER ENGINE RUNNING FOR ABOUT 30 MINUTES, OIL LIGHT COMES ON. ONLY SPEC I FOUND WAS 56 PSI AT 3000 RPM.

I have the same specs.

I looked at the oil pressure switch specs, which stated that the threshold is 2 psi for the light to come on. If your gauge is accurate at 6 psi, then those results suggest a possible switch.
