Just a quick update. I saw on facebook where a guy was having problems with a CB radio causing interference. Someone suggested unplugging the ICP sensor and trying it. So I figured I'd try it to see if it fixed my radio tower interference problem. It worked! Plugged in, the truck spit and sputtered and even shut off if I was close enough to the tower. Unplugged I had no problems what so ever. I noticed it had a new ICP installed when I got my truck so I assume the previous owner used a cheapo parts store ICP. I'm going to get an ICP from the Ford Dealership and hopefully it will take care of it for good.
