Bad secondary ignition (cables cap rotor).... Gets damp and the spark goes to hell?

[Devil Inc]

Good idea DCColegrove, I didn't think about the ignition being damp.

[VAPORBLADE]

cold start valve?!

Kind of thing you think of after years of weird car problems day in and day out...

It also takes higher KV to fire a plug on a cold engine aggravating a "leaky" secondary problem...

Could be all kinds of things though...

oh yeah its a 1984 318i

i just downloaded a sheet on how to disassymble the warm up regulator.
but i would like to know where the cold start valve is.

im pretty sure its not a spark wire problem. i have a clear dist cap and i see the spark
