Anything look funny on these autotap logs ???

hey guys , I got some autotap logs of my car and was wondering if I could get a couple of opinions on what might be causeing my car to run so badly. It seems down on power and the car smells rich . The pcm is pulling fuel on both sides except when cold the 1st bank adds a lil. It runs rough and is either missing or detonating when it gets warm , it gets worse the warmer it gets. The problem also seems to be getting worse and worse.
Ive eliminated my egr system recently thinking I had a huge air leak but I cant find anything (my old worn out vac guage said 11"s but im starting to think its faulty). The autotap log shows good vacuum if you ask me. If you can look at them please offer and I will email them to you or if someone could host them that would be great too.
