[s-cars] POS Question

[Paul Gailus]

I agree.
The coil has arc tracking over the surface of its molded
plastic insulation, and it even looks like there is significant
spark erosion and pitting near the spark plug connector.
In other words, that coil and connector are toast.

It also appears that there's a little more than the normal
amount of surface rust on the coil laminations, so you
may have gotten some moisture in there too.
That could have initiated the problem in the first place.
Do you still have the O-ring gasket in place for the
coil pack assembly? And even if you do, it may help to get
a replacement. After the coil is replaced, it would be
good to do a little cleanup of the plastic insulation on
the other coils. WD-40 should be OK since it's supposed
to displace moisture.
