Sorry photos in wrong order, bottom picture is the start, then going to full throttle. Any advice much appreciated.

Sorry I can’t attach the video it’s larger than 10mb. I will try a work something out

Please help, my daughter’s 2015 Citigo is running massively rich. I have scanned the car with VCDS and the fault code 18105 catalyst system; bank 1 P0420 00 [01100000] - efficiency below threshold intermittent - not confirmed - tested since memory clear. I have attempted to check the oxygen sensors with vcds. Please see attached clips. Can anyone tell me if these results show the oxygen sensors are ok. Any ideal what could be the problem? I am reading the results as when the car is in full throttle it’s running 25% rich?

Hi, I know this is an old post, but does anyone know how to fix this?? I have the same problem.
