I think i Have found a solution for you. first the problem was not there before changing the oxygen sensors. now lets take a step back and let me explain sensor before the CAT is actually an Air fuel sensor (wideband) and after the CAT is always the oxygen sensor (narrow band). Are you sure that one before the cat is an air-fuel sensor becouse if it is an oxygen sensor it will still fit and you will not have any error codes but will not work properly. hope this helps and if am wrong you still will have something to try before changing any more parts and when you cut the wires to change the connector is what made me think that sensor is not working properly or its the wrong sensor for that place

Hello my dear friend, many many thanks and appreciations for your great help and very important steps to figure what is causing this rough idle, actually yes I have cut 02 sensor I think the one after CAT converter and I installed 02 random sensor it didn't work check engine light still on, but after I ordered 2 brand new sensor before And after CAT upstream and Downstream from Aliexpress check engine light gone but rough idle started after that, so you are right it could be wrong 02 sensor not wide band sensor and sending wrong signal to the computer, I still have the old before CAT wide band sensor, I will try to remove the new one and install the old one back on , if this Wil fix the rough idle, you saved me money to time and many more work on this suv Honda , I will keep you updated 😀,, thank you so much again and all the best, keep in touch, 👍🙏
