Yes, did you also feel mis-fires? Are you running a tune? If so, try clearing adaptations and clear the codes and see if they return if they do it could be a few issues from injectors to bad o2 sensors

yes running a tune. how do you clear adaptations with the bt?

i did feel a misfire here and there but only on part throttle. it seems to have gone away lately.

Yes you need a BT, but if you have a Procede, I think shiv is adding this feature soon.

They stay on regardless of meth activation. Do you think this is the cause?
It's strange because my setup has not changed in four months and all of a sudden i get the codes and now they will not go away.

I get these intermittent codes and I just reset my adaptations about once every 2-3k miles.

do you just reset the lambda adaptation?
do you change the adjustment on the v3 fix before doing so?

reset lambda adaptations and codes were back within a few minutes or 5 kms
stuck.
