CHEVY LOW OIL PRESSURE LIGHT/3.8 ENGINE

2002 Chevrolet Monte Carlo

Engine Mechanical problem
2002 Chevy Monte Carlo 6 cyl Front Wheel Drive Automatic 77000 miles

Engine resently had head gasket and intake gaskets reaplaced. Had no problems until after changing oil a couple times

After doing this The low oil pressure light comes on when you stop at a light or remove foot from gas peddle. We noticed the RPM's is low. Would this cause the engine to have low oil pressure. We already replaced Oil pressure regulator valve, and the Pressure sensor. We had a pressure gage put on it and it was reading only 8 pounds. RPMs are running between 5 and 8 RPM's at idle. Is this to low and would it cause the oil pressure light to come on.
Cluster was checked also, and is fine. If idle is to low we know it has to be set by computer. We were also told oil pumps dont go out on these cars
