After installing catless DP's, Im throwing all these codes: 2c9c, 2c9d, 2c9e, 2c9f.
They all about O2 sensors. Auto clear on JB4 doesn't work. This issue happens again.
I know when you are running JB4 - you don't need any external DP fixes, since auto clear deletes everything.
Please help me to find the solution.
Appreciate your any help.
Contact Terry on N54Tech, he will help you with any issue with the JB4
