I have 2010 traverse LS
Few days ago I found check engine light on the truck and upon scanning with obd2 I found code is P0430.
Before rushing to catalytic converter I inspect the truck and found cracked intake duct which is replaced and I also cleaned the throttle body as it was a bit dirty.
Than I cleared the code and kept moving as there was no performance issues Regardless of P0430.
After clearing the code second day the code appeared again Bang Head.
I cleared the code and took the vehicle on a long &hard run after that I found a little improvement in bank 2 O2 sensor's reading and I cleared the code again.
Now often when the truck is running low speed the code appear again but on hard run or high speed nothing appear
Attached are some screenshots at idle!
Please guide me what's wrong here !!!
