I have a cly 4 misfire problem. It happens every 4000 - 6000 miles, and my explorer will start to miss, and then throw a cly 4 mis code. When I pull the plug it will always have a hairline crack. Change the plug and the problem is gone till another 4000-6000 miles. I have included pics of the last two plugs I have changed. The plugs are Autolite APP 103 Double plat.
