coil sparking

[ger]

I started my sled today to move it and noticed that one of my coils was sparking at the top between the boot and head(small spark)

does this mean it is screwed or just need cleaning /servicing .

Not alot of miles on this

or I guess I could say spark plug boot

Clean them with brake cleaner, remove all the black debris and use DIELETIC grease on plug and coils and they should be fine...

thanks , I usually do that before the season but I have never seen them spark before either

while on this topic... how hard should I pull on the coils? those things are on there and I dont want to damage them to get them off...

after unplugging the wires, twist and lift up at the same time to remove. clean inside and outside of coil with brake cleaner to remove carbon dust.
