im a learning mechanic and im not familular with alot! ive looked and looked to no avail. i have many questions lets start:
I have a p0171 code 1bank too lean i have a obd2 with live data but i cant find a vaccume leak anywhere one of my o2 shows the v at 1.275 and stays there. all rest seeem to fluctuate normally. I see that o2 sensors are located under neath around the catalitic converter but i dont know which is which or what to try or even if o2 is my problem instead of intake manifold gasket which is a common problem aswell as the torn elbow i dont see.
i tried to blow smoke in there but dont see any escaping. i checked the MAF sensor but it seems clean to me and reads on obd2 live data.
its hard to start on cold mornings other than that idk. my fuel trims are high for bank 1 like 20 something.
what should i do?
