Hi Guys, I have a 94 Altima GLX, yesterday when we were driving on the road, the Malfunction Indicator Lamp(MIL) cames on, and later I unplug the battary for couple minutes, it doesn't work. Oh, I checked oil filter cap, oil and colent level, and the air filter looks good, and the engine's sounds normal, does anybody had experienced same problem or have any idea?
