Question about 1996 Chevrolet Cavalier
1996 2.4 cavalier working on only 2 cylinders. spark plugs have black build up on them what mite b the problem
Your plugs are fouling out probably from excessive wear on the piston rings. Replace the plugs and check them in about 3 days to a week and see how bad they look. Clean them if necessary and reinstall them. Your engine will burn oil that slips past the rings if they are worn. Usually this will happen when the engine is cold and the rings have not expanded. The expansion is normal so what I suggest is at your next oil change use 3 quarts of the regular oil that you use and 1 quart of 20w/50. The thicker oil will help seal the rings a little better. Don't use more than a quart or 2 at the most because it will make your oil pump work harder causing premature failure.
