Chris, I just completed moving the coils (1 to 3 and 3 to 1). If it codes P0303 then I know it is the coil. However, if it still codes P0301 then it points to the plug. That is my logic. However, please educate me as to the benefit of moving the plug too from your point of view. What should I look for with the spark plug? I hit a deer which knocked the head light alignment out (whew, that was all). I took it to the dealer to align and to put new plugs in, so I hope the dealer installed the right ones.

I did find one curiosity when I made the switch. The number one hole and coil boot was all dirty with rusty looking residue, the number 3 hole and boot was clean. I am wondering what could have run down there. In october I had the timing belt changed. I am wondering if when the coolant reservoir was moved out of the way some coolant could have spilled and run under and down around the boot. Perhaps some water from washing the engine bay got under the spark-plug cover via the timing belt cover. Perhaps the number one spark plug is faulty because of that.

We will see
