TOOK MY CAR TO THE DEALER AND WAS TOLD THAT I NEED TO REPLACE O2 SENSORS. DEALER'S CHARGING ALMOST 4 HUNDRED DOLLARS FOR THE JOB. CAN ANYONE RECOMMEND A MORE COST EFFICIENT WAY TO DO THIS? CAN ANYONE RECOMMEND A SITE WHERE I CAN PURCHASE THE SENSORS FOR A GOOD PRICE?

THANKS IN ADVANCE. ALL YOUR HELP IS GREATLY APPRECIATED!

You can try Rock Auto. And it's fairly easy to replace Oxygen sensors. I suggest that you buy those special wrench for turning these Oxygen sensors. Get some penetrating oil ready because the old one might have frozen already. Check the wirings while you do the job as well. Don't forget to determine the correct sensor, our Cat have 4 if I am not mistaken. 2 are placed before the Catalytic converter and 2 are after. I believe that the front are different from those after the converter. Anyway, you also have to determine which side to replace so you wouldn't be replacing the wrong one.
