P013A - Rear Oxygen Sensor Slow Response Rich to Lean Bank 1 Sensor 2
P013E - Rear Oxygen Sensor Delayed Response Rich to Lean Bank 1 Sensor 2

Whenever I clear the codes they come back pretty quickly.

I'm not sure if this is related to the VRSF DP fix itself, or if something got messed up with my oxygen sensors during the install. Anyone able to help?
common issue. hard to pin point it.

the sensors are very sensitive. the install is straight forward and simple.
done correctly and by the book i've never had any issues.
i'll see what i can find out.
u running e85 by chance?
