So I have been working on this truck since Tuesday. Cannot figure out the problem! My truck will start fine, I will go driving but as soon as it is good and warm and I come to a stop, it jerks and sounds like it is out of gas then when I put in park it’s fine. But if I put it in drive while it is warm it will keep doing it until I turn it off and let it get cold. I have changed the idle air control valve, replaced the fuel pump, changed the air filter. A code shows for the bank 1 sensor 2 o2 sensor. So I am changing that when I am done typing this. If that does not fix it what else could it possibly be? Please help

The O2 sensor is probably okay the code comes up because of the way the engine is running - misfiring. I would start with a full tune up using OEM parts and I would service the throttle bore.
