So I was driving home from cali to Texas and before I left cali I changed all the fluids, spark plug and serpentine belt. I made it to Texas, but as I started to go up a small bridge my car just lost power. So I checked my spark plugs and my #3 cylinder coil pack and spark plug was destroyed. I hade to put a rethreat sleeve in the cylinder cause the spark plug threads were gone. The coil pack harness clip are melted. I bought 4 new coil packs and put a new thread in the spark plug that blew out, but now my car isn't getting any spark. What could the issue be?
