rpm jumped up but this time car started slowing . It
kept sputtering until it eventually died . Parked in a
person's driveway .the car will not start since. I

repeated attempts to start it. The car has a timing
chain plus the normal serpentine belt.  Both look
fine not broken I took a wire off of one of the front
coils and saw a orange spark..  lost at what it could
