Hi guys,
I have a very weird fueling issue. Even when idling and pressing a little bit of gas pedal I get o2 oscilations of up to +12% enrichment. Nothing in GK module relates to this, only fr_w is asking for richer mixture. Anyone had similar problems? Or should I just start disassembling precat o2 module? Suggestions on which variables to log to get to the bottom of this?

P.S> my ltft and stft are within few percent

P.S2> Air pressure tested my intake. Zero leaks.

P.S3> As you can see mass air calculated also looks ok, so maf is ok I guess...
