Thank you for the enlightenment. While that is all well and good, the majority
of fuel related stuff on the I5 turbo is on the exhaust side of the engine,
not the spark plug/ignition wire side. My premise was based on the most likely
location of a fuel leak on this engine design, not theory of combustion.
I seriously doubt that the spark I am seeing is at full voltage potential,
hence full heat, since the plugs are firing and what I see is apparently an
inductively coupled stray voltage (again only at idle) since AFAIK the metal
shrouds on the O.E. plug connectors are not physically connected to anything.
I have almost eliminated this by tightening the connectors onto the wires (a
few were a bit loose) and by routing the loom a bit. I do have some experience
dealing with this from the P-car years as the 911 is notorious for cross-
firing plug wires. BTW, on the 911 you do have the cross firing plug wires
*and* fuel components in the same vicinity.
None of this answers what was a very simple question. For the fourth time
now...what plug wire end connectors work best for people who use the FD5POR
plugs on the 10v turbo??? This really is a simple question that does not need
to turn into an "engineering thread." ;-)
