Was talking about the o2 sensor.
It's mostly city driving and I'm not on the gas much at all. Can't figure out the gas milage issue... I cleaned my air filter (was really dirty) and maf but that didn't help. Should I pull the battery after to reset the fuel trims? I also plan on pullin off the throttle body to clean it this weekend.
Here are 3 scans I took yesterday:

Sorry to bump an old thread but I though I'd give an update.
Gas mileage issue was fixed by cleaning my throttle body, maf, cone filter, and going up a heat range in plugs (AL605s). I could literally scrape chunks of carbon off the throttle body with my fingernail that's how bad it was. I am going to have the egr tuned out so I don't have to deal with that again.
I've been off the gas the entire time with my knocking issue and I just discovered what was wrong this last weekend. I was very ignorant about the pulley I was running. I was having a friend put on a MPS this past weekend and he made a comment right away before we started that my pulley was much smaller than stock. We took it to the digital micrometer after it was off and it was a 3.3" pulley. I've been running that for 2 years with nothing but a 180tstat and cold air intake. I really had no experience with superchargers beforehand so I had no reason to not believe it was anything other than stock. Anyways, I put on a 3.6 now and will be putting in AL104s once again and I should be completely knock free afterwards.
I bought my car used about 3 years ago. The guy told me it was completely stock and that he's never had any issues at all with it. Well after I've bought it so far I found out that it was in the dealership and had piston issues and had it all rebuilt and that it had a 3.3" pulley on a stock motor this entire time. I don't know how the hell it lasted this long and I'm lucky I caught it now and that I haven't been beating on it too much over the past 3 years.
Learned my lesson(s).

I wish I knew half as much about these cars back when I bought it as I do now. At the time I was looking for a low mileage car that wasn't overpriced. Bought it for $13,500 with only 30k miles on it. The guy actually owed more on it than what he got for selling it. I guess I know why now and learned my lesson the hard way. I can't complain much though, it's been a very reliable DD so far with no major problems (knock on wood).
