My car was running decently until the upper waterhose broke and sprayed water everywhere under the hood. As soon as I replaced the hose and cranked the car it was missing on one cylinder. The first thing I did was to replace the plug wires and it didn't help anything. I installed a set of Motorcraft AZFS-22PP at about that time, too.
Not long after this and before the missing ever stopped, the tensioner for the timing belt broke. This was in March of '02 and I let the car sit on the driveway until early August of this year. It wasn't until I replaced everything having to do with the timing belt and got the car running (kinda') again that I delt with the miss. In the long run it turns out that it was the coil pack causing the problem all along.
Since I only installed the new coil pack last Friday night I have not had time to pull the plugs and examine them.
I will add this...
It was the #1 and #4 plugs that were cracked. Those plugs are also tied together in the coil pack because the secondaries of the #1 and #4 coils are tied. Eventually my #4 cylinder was completely dead. I read in another thread that a bad coil pack could cause cracking. Maybe so?
