At idle, the needle of the oil pressure gauge in my 84 Cutlass H/O bounces wildly. (I replaced the sensor a while ago because the old one sprang a leak and pumped out most of the oil in the pan.) I suspect there is capacitor in the gauge that dampens the needle movement to prevent this. Can anyone verify this? I can't recall if the gauge can be opened up or if it's riveted shut.
