How's the condition of your motor mounts?

How about the routing of the spark plug wires? Did you follow the factory routing using the factory stand offs and looms? Touching any metal parts? Looped over anything that puts pressure on the wire?

Thanks I will take a look and see if its routed like the factory

Is that 01+ GT style hood scoop on your GT?

Now this is something I have never seen before. Are the plugs wires "jumping" off the plugs or the coil packs? Was it doing it before you washed the motor? Maybe water got down in the plug holes causing some kind of odd electrical surge? I know that if they are coming off the coil pack cheap wires sometimes wont go over the coil pack terminal well and will slip off, causing a miss-fire. I had a set once I had to really work with one particular wire to get it to click on the pack like it should, and they were Motorcraft...
