tuners (o2 sensors)

o2s

You won't loose power even if the light comes on. Its just anoyying. The rears have ZERO effect on fuel trims and performance, they are simply there to see if the cats are doing their job. The fact that you have no light or any codes is nice. If its not broke, don't fix it.

cool i guess im lucky with this one.....455/457 has had my lite lit for 6yrs...how long does it take for a bulb to burn out?

that works well on chevys but i have NEVER seen it work on a ford. i have tried that method with 5 different cars with no success. i've even doubled up on the foulers and it still didnt work

Hmm, worked great on my car so idk??? I also know other's who've done it on Mustangs and it has worked.
