Well since you just got the Lambda sensor done i'd imagine the most likely cause is either the new sensor is slightly longer than the original and hitting the heat shielding or in due course of fitting the sensor the exhaust was moved/twisted untill it hits something. I suppose its also possible during the fitting of the sensor that an exhaust mount on its last legs has perrished and the exhaust is having a dance under there!
