Downstream oxygen sensor on the passenger side. Do you have headers?? If you do remove the sill and check the sensor.

You sir have a PM

No headers. Not sure about the cats as the car is louder than a stock gen 3. Have ordered a corsa catback and will pull the sill when it arrives.

The car does buck a lot at lower speeds (more so when cold) requiring frequent clutching.

It is the o2 sensor I have a PO156 code which is the other sensor on the passenger side and my car bucks at cold temp too, once warm it goes away, I just let the car warm up in the driveway before I drive it, I will be swapping it out too when my new exhaust arrives

New exhaust installation cured the problem.
