A/F Correction #1 fluctuating

[SpecBinNB]

Hey guys I was wondering if any of you can shed some light on why my A/F Correction #1 is fluctuating so much? It's been driving me nuts. Drives fine with moderate load but when cruising or light load I can watch the L/100km needle in my cluster swing like a pendulum.

 

Both O2 sensors have been replaced with no change, and a new MAF as well. Boost tested and no leaks were found.

 

Could a failing injector cause this? Bad spark plugs or a coil?

 

What should I look at next?

 

I've attached a couple logs.
