Hello Scotty, My truck is acting crazy. It's stalling on idle and when I give it gas, it jerks. We went and had it tested and the code that came up is PO172, fuel system (S1, B1) rich. It says to get a new oxygen sensor but we want to be sure that's what we need precisely. If you could please get back to me asap, I'd appreciate it. Thank you so much. -Erika
I need help finding the bank 1 sensor 1 O2 sensor on my truck. Where is the exact location and Step by step how do I get it off? Please and thank you! 🙂

16 year old truck, probably dirty or clogged fuel injectors, fuel filter, MAF sensor.
But how can we know for sure which one it is? It also only hesitates on take off but while running, it is fine.
