The yahoogroups address is bogus.  The alfa@domain.elided address is all you
need.

Doesn't sound normal to me.  Sounds like you've got a bad ground somewhere.

I think another digester recommended you clean the injector grounds.  With
any V6, I'd absolutely clean and detail those, plus any connections to any
senders at the front of the motor, plus any grounds in the engine
compartment in general.  There are so many V6 problems caused by one or more
of those connections going bad, I'd almost always start there first.

Dumb question, but have you checked your timing?
