1997 Mitsubishi Montero 6 cyl Four Wheel Drive Automatic 117000 miles
good day! I just bought a montero 1997 and I noticed that the check engine warning light goes on for a few seconds even when the engine is already running. I also noticed that volume of smoke emitting from the exhaust pipe is greater than normal. The smoke is white and is accompanied by water. I have changed the spark plugs and noticed too that the burning of fuel is good as indicated by the spark plug. The warning light does not stay on. What could be the problem?
