well try this instead...

tonight after dark, go outside and pop the hood. look for any arching from the wires. look at the spark plug boot and look at the wire itself. the wires doesnt actually have to be black and melted completely to be burnt.. all it needs is to be touching something hot for long enough and that area of the wire will start to ground to whatever its touching.

 

if you don't have any arching, i would make sure you have a good connection at the opti with the wires. this has caused a few people similar problems. just a guess, but you did just change the opti so check the connections.

 

I got everthing finally fixed. The wire had come out of the loom and was sitting on top of one of the pullies. I couldn't see any arching in the dark, but I was like oh they fell out of the slots, Let me put them back in. Drove it to the store afterwards and was like oh damn it's working. Thank's for all the help guys
