2001 Ranger Oil Gauge Flicker, Very rattly engine.
When i'm driving, and i stop at a light or sign, the oil gauge goes ballistic, and flickers back and forth so hard it seems like itll break! it used to only do it a little, but today, it just went all OUT and nonstop. and the engine, (3.0 L 2001 ranger XLT 4dr) is super rattly & sounds like its definantly working harder than normal. but the oil is full and clean, i'm not sure what kind, i just got the damn thing 2 months ago. been running great! i read multiple threads on here about it being low oil pressure? but i dont know. any help is greatly appreciated!
