Just bought 3.0L Auto , lovely car, had an issue with spark plugs so have replace all of them with new ones,
have OBD alert on the 02 Sensor Bank 2 Sensor 1

its been running fine up until a few days ago when now if i hard accelerate from standstill i get a judder for about a second and then its all normal after it seems to change into 2nd gear.

Would this be the 02 Sensor affecting anything. or the transmission?

Any help would be appreciated
