OBD2 codes

[Phils I30]

I just bought a used i30 3 weeks ago. I love it. Lots of power and response. I just got an SES light and had the codes checked. One is a P0325 and the other is a P0153. I have been trying different gasolines to see if I experience different performance. Any clue to solutions to these. I have a 6 cyl. 3.0L engine.

Replace Oxygen Sensor

I'd recommend replacing your oxygen sensor which should be easy to get to under the hood near oil dipstick.

Here is some info from http://www.obd-codes.com/p0153
P0153 OBD-II Trouble Code --- This involves the oxygen sensor upstream the catalytic converter on Bank 2. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.

Would the oxygen sensor cause the car to run sluggish
