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

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

              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

                  Still have the 2002? Drive it instead.
