Hello guys, help me before I go crazy . My car honda accord 2003 Euro threw the P2195 code, air fuel ratio sensor signal stuck lean and it started gulping fuel because it is now on open loop. at first I tried to change the sensor and we tested more than 5 sensors same code. We always Clear before scanning.

I have fixed my exhaust leak, it was welded and the cone was changed. I tried to use carb cleaner to spray the engine for air leaks but nothing, no sudden rev while spraying.

I'm stressed out, we've been on this for 2 days now. Today, we've also tried 3 other sensors. I am pretty sure this is not a sensor issue anymore. What else could this be? Any insights or help would be appreciated. Could it be an electrical issue? I am lost at this point..
