Some diagnostic help
Hello all!
Im looking for someone who is able to read live data. i have been trying to learn to read this stuff but dont understand it yet.
Anyway I have a 2003 Z and I think I may have an issue but I am not sure because all of a sudden the car really smells rich of gas while running and I seem to have some power loss. I have test pipes so im used to some gas smell but it has doubled in the past few days and the power loss. I have 83000 miles and mods are Takeda short ram intake,Momentum ypipe with cat delete using stock mufflers. Below is the live data warmed up at idle if someone could just take a quick glance and let me know if anything jumps out as wrong it would be greatly appreciated! Below are the readings. Thanks again

Your STFT B2 S1 -6.2 is a little rich, but the 02 Sensor voltage looks good at 0.390. Your spark advance at idle (14) looks good, but what happens when you hit the throttle (say half way)?
Otherwise, I'm with cobra... looks good.
