Low Oil Pressure Gauge

Greetings all,

I have 1998, 6 cyl and i just noticed a intermittent "low oil pressure" gauge problem. the light on the dashboard says to check gauge.
sometimes the pressure gauge works fine, sometimes it's low just above the L and sometimes the needle bounces up and down while driving or at idle. the oil level is full and the oil is brand new.
do i have a serious engine problem here?

I'd would bet/hope for a bad oil pressure sender or the wire that runs to the sender is in poor shape.

FYI:
thank god, it was a bad oil pressure sending unit ($8). i just replaced it this morning.
i had a heck of a time finding it. on a 6 cyl 4.0L engine, the sensor is located on the drivers side, down low near the front of the engine block. i had to take the left front wheel off and remove a mud flap to get to the unit.

I thought you said you had put a mechanical gauge on it and it didn't read any sort of oil pressure.
