new plugs? new wires?

[snipez]

my car is hurting when its warm out.


battery dies, or close to it. engine is laggy

how can i tell if i ned new wires and plugs? i replaced them 35,000 km ago. i take one boot off the coils and it looks like the coil head burnt a mark into the wire.

could it be rad related? even though car dosen't overheat

coils are fine, vacuum tested the heads, fine

fuel injectors seem to be all in order

anyways, any ideas?

New wires might be good since you've indicated that there was arching going on. If there are burn marks, that may suggest arching which means that at some point the boot came loose and the spark began to "jump" and in turn burnt the wire boot.
