Great job! And the timing of posting it couldn’t be more relevant to the work I’m currently doing on my Ram 1500. I’m finally on the driver’s side warped manifold replacement after just finishing the passenger side. I’m going to check my O2 sensor and catalytic converter to see if that’s why I’m getting misfire codes. I’m praying that it’s not the lifters and camshaft.

Nissan doesn't call their upstream sensor an O2 sensor. It's called an air/fuel ratio sensor and it gives a P2A00 code for bank 1 with a check engine light. But other things can cause which makes it frustrating to isolate. I replaced the sensor and still get the code. So it could be a vacuum leak, an exhaust leak, or who knows. Starting is fine. No black exhaust. Idle appears to be OK. No real hesitation. But the Bank 1 Short Term Fuel Trim is high; hovers around 15%+ . I just wish the code pertained to one thing and not the result of being effected by other things.

I got a question for you, but I am not sure it’s relevant to the o2 sensor failure or not.
My question to you is this: My vehicle sometimes takes longer to start, I smelled terrible exhaust smell mixed with gasoline this afternoon when I started it, so I also have problems with acceleration, because when going from 45 to 50 mph and higher, my car jerks and RPMs fluctuate on the tachometer. Can all these symptoms relate to a bad oxygen sensor? I would like to know, because I am afraid to take the car on a highway. Please let me know. Thanks.

Ok I don't have a code reader and have run into an issue with my 2011 camry. The first start up in the morning is great. The engine cranks right up. After I have driven it for a few miles 10, 20 or 30 and let it sit for a moment it cranks, cranks and cranks then eventually starts up. I recently put in a new battery and replaced the air filter. Any suggestions where to go next?
I've been told the fuel pump, but the car idles and runs great other than the start up on a warm engine.

Very interesting.. I'm getting a P0171, though I suspect it's from an exhaust leak.
Damn car is getting 16L/100km, which isn't ideal.
If it had cats, they would be stuffed by now. I'm not putting them in until I get this issue sorted, though.

What if i remove it completely, what are the side effects?
