You got a few issues. looks like you have a exhaust leak, injector or a lazy 02 due to the uneven LTFT at WOT. You may need to log fuel pressure as well. you really need to get that fixed.

fuel pressure is 57 under full throttle, no exhaust leaks anywhere. has to be catalytic converter.
I gave up. dont have time to mess with it. its either going to be a plugged cat or both, or bad injector(s). Going to a shop tomorrow. It sounds real muffled out of the pipe and sounds like a slight miss. I will post back once I figure it out. It got progressively worst since last week and now when you punch it from about any speed it just bogs and gains about 1 mph per 2 seconds- could easily ride a bike faster. I have never seen anything this bad, so if someone else wants to chime in confirming my thoughts on the cats being plugged.
