Oil Pressure Problems
Oil Pressure Problems My oil pressure gauge shakes when ever I am sitting a red light or anywhere else. just shakes enough to notice maybe 5-10 PSI. I have changed the oil and also changed th spark plugs and My RPMs are at 500 when Idle. Just trying to figure out what it is the car shakes when sitting and feels like it may stall sometimes but never has. the car did shut off on me goning down the road at about 50 and then it started back up which freaked me out so I pulled over and checked everything and then drove home. I used NGK TR55 plugs, Fram filter, and Valvoline oil. Thanks for the help and I hope someone knows whats going on.

Oil pump screen loose, plugged, or damaged
Oil pump screen O-ring seal missing or damaged
Malfunctioning oil pump pressure regulator valve
Excessive bearing clearance
Cracked, porous, or restricted oil galleries
Oil gallery plugs missing or incorrectly installed
