Hello BB Forum:

My wife's 2002 V70-2.4T wagon (230k miles) has been idling rough (and occasionally stalling at low RPM) but otherwise running fine at higher RPMs. It threw a check- engine light over the weekend. OBD diagnostics came back with codes P0134 and P0234, which apparently is the "Bank 1 Sensor1" O2 sensor and "Engine Overboost Condition". Anyone know how hard (or costly) it is to replace the sensor? I hear that they can be expensive and a pain to get loose, even with an O2 sensor wrench.

Thanks.

Bernie
