Re check your MAP and IAT sensor. If there not reading right, your ECU will not know how much fuel the engine need's. Good luck

• An Oxygen sensor sniff for fuel to adjust the fuel to air ratio. When they go bad the run lean all the time. So you don't get sufficient fuel. So if the code read O2 sensor then you should change one or both out. It's not to hard. Thing is there are two O2 sensors on your car. You have an Upstream and a Downstream. The Upstream is not far off the manifold and the Downstream is down the exhaust by the Catalytic Converter. It could really be either one. I put a video up on how to test an O2 sensor. If you don't have the proper gauge then you can rent one or replace one and if need be replace the other. If the vehicle has set for a while and is not performing right it might not be a bad idea to put both on. It's not to hard to change the O2 sensors. You pull the connector off it and put an O2 socket on the end and twist it out, like you would a spark plug. Then replace with a new one. I would start with the one on the exhaust not far off the manifold and then if need be move downstream. Sometimes you have to move a thing or two out of the way to get to that Upstream O2 sensor but it has to be done.
