i don't know but i have a 88 f-150 with a 4.9 w about 125000 miles on it and it does the same thing rides just to left of the n in normal. i spoke to an employer at a Ford dealership and he said that it was nothing to worry about. he said it was just a bad sending unitand the gauges are just idiot gauges and as long as there is some needle movement in the gauge than there is enough oil pressure. that's why they just have the big "normal" area on the gauge and no acual numbers to compensate when a sending unit is putting out a little more or less volts than it should be. the needle remains in the normal area. but is long as the needle moves at least in the normal range there is nothing to worry about. this coming from from a ford dealership mechanic
causes of abnormal pressure
the force with which what the contract causes blood pressure
It causes blood pressure to increase.
Modern lifestyle is full of stress. It causes so because of the pressure. Pressure in lifestyle, Pressure at workplace.
Weight causes density, density causes pressure, pressure causes heat. Heat and pressure change rocks into other rocks, which are metamophic.
Heat. The addition of heat causes expansion and spreading of the molecules which in turn causes an increase in pressure.
It causes the Bourdon tube to straighten.
what causes air injection system pressure to be stucked in cars
I have a science test this week and was wondering what causes air pressure differences on our planet?
No. Low tire pressure causes poor handling and poor tire wear.
Uneven heating in the atmosphere causes pressure differences and when air is in high pressure, it moves toward an area of lower pressure, and that is how wind starts.
Check the fuel pressure regulator, vacuum lines, ignition components, exhaust components.
