Thought I designed my page (http://6007.us/coils.htm
) to print in letter mode. If having difficulty, you might try portait mode (file/print/basics or layout, look for checkbox).
That said, an arcing plug wire or cap to ground will often make a ticking sound. I would suggest pulling the plug wires and looking for frayed spots or carbon tracks. In that case when the arcing wire is pulled from the coilpack, the ticking will stop (or move to the coilpack). ARC may also be visible in a dark agarage.
Sometimes we get so wrapped around the high-tech electronics that we forget the old-timey problems.
