I have a 2001 3.0 with 75,000k on it.. I had been having the C E L flashing when I get on the freeway... Then go off when I exit the freeway. Had code read, P 0303.... The other day I drove and the light came on and stayed on... Code was now P 0303, P 0304,& P 0306. Yesterday I pulled the plugs & #4 electrode was gone down to the ceramic and looked a bit oily. I thought for sure that was my problem so I put all new motorcraft plugs in. I started it up and I still have a dead cylinder. I didnt run a compression check but will do so today. I also thought while I have the plugs out I will put them on the wires and ground them on the manifold and see how the spark looks. I'm hoping to read some suggestions. Could the coil pack have caused the problem and if so how? Cam positioner? C E L is flashing and then goes solid again. Drive to the store and it flashes..... Start it up and it's solid... Drive it and it flashes.... Can you all share some of your thoughts on this with me? Any and all thoughts shared on this matter is greatly appreciated....... Thank You................ V
