rear left o2 sensor is bad on my baby (97 2.8 QM). i was told it would take one and half hour to replace it. i know the connector goes very deep underneath the hood and it won't be easy to do the job without a lift. however, did the mechanic exaggerate it? could it be done without disassembling other parts in the way?
thanks in advance

 

that just a labor cost? If so its not rape, but it's not a good deal by any means.

 

the rear o2 sensor is easier to get to than the pre converter sensor. $100 really is not too bad though.

 

thanks for the replies. 100 is just for the labor. he asked 210 for the sensor. that's rape.
seems it won't be a easy diy for unexperienced player anyway i will try to see how far i can track the wire into the hood. if i replace it, i need to erase the faulty code with an OBDII scanner before i turn on the engine. right?
