My father in laws 05 Adrenalin has a misfire. When I first got it from him I was getting a P0303. What is odd about it is that it only does it for about 10 seconds on a 20 mile drive. The CEL will flash but not set except one time. I tried plugs first, the only difference seemed to be the P0303 went to P0300. So I changed the coil pack, no change. I did wires next and it seems to have helped the most. The miss still happened only for about 10-15 seconds and not CEL light or codes. I don't know what to try next. All parts are Motorcraft, I did the wires last because we had replaced them last year with Duralast golds. TIA
