COP= Coil over Plug
The code is telling you there is a miss fire on cylinder 1. This is often caused by a bad coil(COP). However this could be caused by other things like a bad fuel injector, bad spark plug, or an internal engine problem. The coil is certainly the first thing I would look at and is much more commong than the othes I put on the list.

I bet 99% on the plug and 1% on the COP...
Dead COP is rare unless Ford messed it up. For example, on my '98 and the #4 COP: it broke twice and later I found it's the AC line on top of it dripping condensed water on it!

swap the coil pack with another cylinder and see if the code shows up on that plug. I did that on my 05 and found it was the plugs.

Like brodi said, swap coils. Disconnect the negative battery cable, swap coils # 1 & 2, connect the battery cable, go for a drive, and see if the code moves to 0302. Motorcraft plugs are good for 100K so they should be fine, if they're MC.

The other thing is, when a COP goes bad it usually not the COP. Usually it is the rubber boot on the bottom of the COP where the insulation elements break down and allows spark to jump sideways. Most auto parts stores have the boots for around $3.00 each. So you might even want to try that route first.

If you can wait a week for them to ship in, you can buy a set of 8 off eBay for about $75.

What do you mean by "no luck?" Did you already switch the COP with another and the misfire remained at cylinder #1? Did you clear the trouble codes after swapping it? If not, the code could be there because of the original misfire.
