O2 sensor issues

Hello,
I have a 2014 Mustang Gt with BBK long tube headers. It has been tuned and running great for over two years. Recently I started having issues with accelerating at about 2500 rpm. Sent a data log to the tuner and they said it was the o2 sensors. I switched the o2 sensors and it worked great for about a day or two and now same thing. Any suggestions? Thank you

Knowing that your running long tube headers, are the 02 sensors disabled in the tune? if not, this could possibly be the reason for your acceleration issues...
Otherwise, I would make certain your 02 sensors that you switched are functioning properly... :dunno:

Have You Tried Pulling Codes?

And if So is Your Reader Capable of Pulling B-Codes as Well as P-Codes?

Also Consider an 02 Issue Could Also Be in Wiring To 02 Sensor and Also These Days Bad Parts Are Fairly Common Place.

I Would Be Curious As To How The Plugs Looked as Well. Are They Fairly Fresh are Due For a Change?

Was Any Kind of Work Period, Done Prior to Issue Surfacing?
