VAVolvo Posted October 27, 2004 Report Share Posted October 27, 2004 A buddy of mine works over at a Volvo specialty shop and I asked him about installing new O2 sensors and he said that I wouldn't be necessary since the ones I already have are still working fine. I've heard that installing a new O2 sensors would improve the car performance a bit even if there is nothing wrong with the old ones.Thanks for any feedback!

ROB @ VMS Posted October 27, 2004 Report Share Posted October 27, 2004 how many miles do you have on them? Link to comment Share on other sites More sharing options...
VAVolvo Posted October 27, 2004 Author Report Share Posted October 27, 2004 how many miles do you have on them?← If they haven't been replaced before, I have 140k. If they have, I'd have to check with the previous owner...he took very good care of the car...but let's just assume he didn't. Link to comment Share on other sites More sharing options...
Mesoam Posted October 27, 2004 Report Share Posted October 27, 2004 I say replace them...Almost guarantee you will see an improvement in mileage. And if you don't see any gain in any way whatsoever at least you have the peace of mind that they are fresh :D Link to comment Share on other sites More sharing options...
