And, to add more....as QSD said on another thread..
QUOTE=quicksilverdon;250542]A lot of us have been owners and on PT forums form many years, and I can tell you that coil problems are not very common. Ignition wires are bad (stock ones), but very few coil problems.

The oil on the plug - the plugs are in deep recesses in valve cover. Each recess has a seal - the valve cover comes off & seal gets replaced. Again, not common, but it happens.

Most ignition problems are the wires,
other causes - cam position sensor, MAF sensor, IAT (Intake air Temp) sensor, PCV and EGR valves, and intake manifold leaks.

No parts on any car are 100%, but I play the "averages" of what's most common first.[/QUOTE]
