o2 sensor diagram

Hi guy, I'we been having issues with my gas mileage, it look's like I'm getting only 12 mpg, it's city driving, but I'm light on pedal. So far I checked injectors all ohm-ed at 12.4, I am not leaking gas I have checked all fuel lines. There is smell of gas coming out of exhaust regardless if I'm starting it from cold or stopped after 30 min drive. I tested my o2 sensors and car test showed something like fine but I wasn't sure. So got Ecutalk free version and it shows o2 sensors working, but I'm not sure if they are operating correctly.

Here is o2 sensor log, can anyone confirm that they are functioning properly and that this is how the log should look like.



Is there any way for Ecutalk or some other free diagnostic software to display if car is running lean or rich?

OK, so no replays. Just o clarify, image in my first post shows o2 sensor operating voltage in time. I took the car for a drive and recorded o2 sensor data.

Here are some of my questions, can o2 sensor be something like slow? Or is it just working and not working unit?

I am guessing, but if someone can confirm that both o2 sensors should operate the same, there shouldn't be any discrepancy between them?

Is it possible that there is something wrong with sensor 1 operation because there is something wrong with that engine side? Or that I might have exhaust leak on that side making o2 sensor to work differently that sensor number 2?

Hm, I replied to this last night but I guess it didn't save.

Those are very irregular readings if those are concurrent files. They should at least be ballpark similar.

OK, thanks for replay, i'll changing both of sensors and see where that gets me.
