Damn Volkswagen Coil Packs

[sailingfc at dslextreme.com (DY Wong)]

Have you tried gooping the top of the coil pack with RTV?  I read this
somewhere.  The misfire is caused by the cracked insulation of the coil pack
and the moist/damp surface.  The spark jumps to ground across the surface.
The RTV puts on a new insulated surface.  I would try baking the coil pack
in a low temperature oven setting first to drive out any moisture and then
slather on the RTV.

Good luck.
