F0x Slaughter

When I enable SD through TunerCats my idle AFR is right around 14.3 on my wideband o2s. When I blip the throttle, let off it jumps up to over 15 almost 16 and stays there and won't come back down.
Also my left wideband likes to bounce around a lot while my right one stays pretty stable. When I put the car in MAF mode the left o2 is pretty stable same with the right one.

Anyone know why this is?
