Does anyone know what that small tube is that goes from the top of the air intake hose, back near the O2 sensor, (it can be seen to the right of it and just behind the transmission dipstick. It came loose during my replacing of the air filter and I thought i got it reseated, but ever since then I've had the "service engine soon" light on solid (not flashing) and occasionally it goes away and performance improves, but other times it is there and the car chuggs a little.
i dont have any overheating issues or coolent but i guess ill just have to buy a need o2 sensor thanks anyways if i have any other questions ill ask thanks
OK i changed one like you did the bank 1 sensor one and my service engine light went off and later that night it came back on and i went to autozone and they say it was the PO135 and he told me they have another O2 sensor i have to change its by the cooling fan but i cant find it

@NolaCTC9 Well p0135 is heater eleiment in o2 sensor. So could be a couple things. 1.
the wiring on the o2 sensor you replaced is not connected right or there is
corroded/split wires. check for that. 2. do you have any overheating issues
or coolent issues? 3. mabey the new o2 sensor is bad. there is only 2 o2
sensors. there is not one by your cooling fan if you are on the 3.1l
engine.

how many 02 sensors they have upstream on the buick sensor

@NolaCTC9 To my knowledge there are only 2 sensors total, 1 upstream (the one shown replaced) and then 1 downstream on the pipe.
