Wastespark ignition (7mgte)

[JustCallMeOrlando]

I'm pretty sure it's to do with the setup and/or chemical thing. Can I find it though? Not for the life of me!

Agreed the coil knows no difference between which plug its firing to. And i think we all agree that one spark is occuring at the top of the power storke and the other is occuring at the top of the intake stroke.

The resistance of the sparking sircuit is determined by the conductivity of the air between the gap, and the distance thereof. Since the voltage is constant, this resistance will affect the number of electrons making it across the gap (current).

I cant find any good links, but i am sure that air under higher pressure or containing more vapours is more conductive than air which is drier or under lower pressure. It affects the plasma threshold...

Anyway, check if no.1 is overgapped (and thus under intake stroke resistance too high - no spark) or else this whole conversation is probably up the wrong tree...

Infact, i cant see (or find) how atmo air would be less conductive than exhaust fumes at slighty higher than atmo pressure. And the plug would have to be really bad not to fire if you pulled it out and just put the lead on, so im buggered if i know what your prob is.
