replacing O2 sensors on Ford V6......

Is it worth it. 130k miles and fuel economy sucks, about 15 mpg.

Is it worth the labor and parts to replace it???

With fuel prices as high as they are now I would sure enough replace it.
For 50.00 to 70.00 bucks and 15 minutes time you can do it or pay at the pump if you don't.

Not sure that an old engine will do much better than 15 mpg city...but it is relatively easy to replace these. Just go to auto store, get sensor, use a plug wrench and swap them out. 1. 2. 3.
