O2 Sensor Life and Replacement
Hi, my 94 has about 70K on it. I am just finishing up the install of the second set of headers (long tubes this time)...
I have the original O2 sensors on the car. I had heard that new ceramic headers foul sensors. This is my second set of new coated headers so I figured I would ask. Is there any merit to this? Is it time to replace them? Are the NGK ones any good or should I got with GM ones?
Any help appeciated - Thanks.

Yeah the coating on the new headers could foul the new o2 senors. I'd wait a couple hundred of miles before installing the new o2s. Heard AC delco are good, I have Bosch even though people said they have had problems with them mine are fine. Hope this helps
