That would probably be why it seemed to all the sudden start idling rough when you first start up. I really wish that thing would have thrown a code before you left. It should be a quick easy fix so long as it's just the spark plug itself. All that stuff is still the original wires, coils, plugs, and boots from adams old motor.

So, who want's to do the write up everything we did, from start to finish? hahah <img src="/forums/images/graemlins/lol.gif" alt="" />
