AZ doesnt loan an oil pressure gauge, i checked. so i bought one from harbor freight today. it flickers when idling. the oil was low the first time it came on and i was due for a change so i changed it. its full now and i still have the problem. the idle is a little low (500rpm), but i wouldnt think the oil light should come on at that speed. ill be checking the pressure in the morning. i hope its just the pressure switch.
