Came home, bound to spend a little diagnostic time tonite.. Was all
prepared to hook up the jumper cables and pick up where I'd left off before.
work.
Hit the key and she fired right up. smokes and of fuel for mayeb 5-10
seconds.. Now back to normal.
Wife asked what was wrong.. I told her she must have just wanted a couple of
days off.
Anyway.. running back to normal.. I love posessed vehicles. LOL

Each time with the same results.. Would eventually fire, and behave like the
