What would cause the oil pressure to drop to zero on a 1994 Pontiac Bonneville while it is idling Now the pressure stays low even when the car is idling high does that mean something worse is wrong?

Your gauge Could Be Reading Wrong, Sender Bad Ect. Other Things If Oil Pressure Is Bad. Oil Pump Bad, Cam Bearings Bad, Crankshaft And Rod Bearings Bad. Have Your Oil Pressure Tested By A Mechanic With A Pressure gauge To Get The True Pressure. It May Just Be A Bad Oil Pressure Sender. Also You Need To Use The Recommended Weight Of Oil. Best Place To Start Have Pressure Tested. Good Luck
