Oil light flickers at idle when engine is warmed up.1990mazda 323 1.6
Have you tested the actual oil pressure? You may have an internal engine problem or it could electrical.
I'm having the exact same problem with mine. I just had new spark plugs put in, a new distributor cap, and changed the fuel filter with little success. The best thing that's helped so far is putting some Fuel Injector fluid in the gas tank (~4.99 @ grocery store). Good luck!
