Today, I decided to replace my plugs w/ champion truck plugs. I went ahead and bought them, and upon removing the boots from the old plugs, two of them cracked. i decided to get a new set of wires as well, and went to the store and picked them up. After finishing everything, I started my engine and it's running very rough. it almost seems like 1 or possibly two of the cylinders aren't firing. are there any easy ways to check what's going on, should I remove the plugs and try again, any ideas?
