Oil pressure or level issue?
I have a 99 ranger reg cab 4cyl manual tranny. I change the oil every 3 thousand. For some reason lately when i start it up the oil pressure or level guage, im not sure which one it is (the one on the same side as the battery level) i have the guages with no TACH if that helps. When i start it up the oil pressure or level guage sits on L and doesnt move. I rev the engine a bit and it just sits there. I gun the engine, dont know how many RPM cause i aint got no tach and the needle perks up and sits in the middle between L and H like it used too. I just changed the oil a week ago and i cant figure out why this guage is acting up. The truck has about 85k miles on it.
