jumpy idle, lean issue

[7m4runner]

I just installed a wideband and I noticed that my A/F reading jump around between 14.6 and 15.1 during idle is this normal? I also just started a problem with my engine leaning out during WOT, Could that be related to my jumpy idle. Your thoughts please.

Jumping from 14.6 to 15.1 is normal op temp idle afr's.

Did you bypass the J-Tube?

What are your WOT afr's?

yes i bypassed j tube,
I goes max lean at WOT, like 18.1 and higher and loses all its power, I have to back off quickly.

It just started going lean on me, It wasn't doing it before. I don't know what triggered it

A misfire shows as lean on a wideband, does not necessarily mean its going lean.
