I took my car over for spark plugs and coil end replacements today. Once he had a look, he told me that I would need new wires after all, he said they looked "arced" (sounds ARK). He also told me to get some new spark plug wire boots? I was in a big hurrey so I wasn't too clear on if those were the coil ends were not. Anyways, looks like I'm going to buy some wires tomorrow before... then finally have the beast prepared for driving again.
I'm guessing that my wires didn't last as long is because of higher engine running also. My car has probably had more engine revolutions, than the average.... in lieu mileage.
