plug wires melted?

[dy5]

i went to pull my plugs out today and i couldnt, so i ripped the wires out and unscrewed the whole plug thing out.
on top of the plug the little piece was gone just a screw thing was there, the hard black plastic was melted. WTF
a month ago the car really hot for a little while. water pump ceased up and i didnt know.
could that be what melted them? could that also be why the car runs like shit? besides the timing issue?

Of course, you may have only been running on 1 or 2 cylinders. I would buy some good wires to replace them. (NGK, Magnicore, etc.) Also, put the stock plugs in if you dont have many mods. (NGK - BPR6ES) If you are running more boost or a bigger turbo, go with BPR7ES.

Hope this helps.
