Ahhh I see, when I added the 1/0 it helped tremendously, I replaced the broken ground with another new one and so far no discoloration on it at all. Before the 1/0 thats when it broke that ground and it was almost copper in color, I guess it's just because it wasn't enough ground before. I'm currently in the garage looking at the o2 sensor ground and its a little toasted looking so I'm going to fix that and see if it fixes my idle issue
