O2 sensor recommendation?

Go drive it to get the pipe hot then try to take it out. The NTKs come with come copper antiseaxe. Use that ont he threads only when you reinstall the new one. Personally I would leave the after cat one alone until it triggers a check engine light.

I remember this thread. :laugh: I have about 20,000 miles on my NTK sensors and new cat converters with no issues so far. Passed emissions a few months ago with flying colors.

I shoved an NTK one into the new to me 90.

so NTK and Renix make sweet sweet love.

My misfire ended up being a broken valve spring. I have a replacement head from Alabama Cylinder, and they use Chrysler valve springs. One of them broke so I had an intermittent misfire.

If anyone needs some used O2 sensors I'll sell them for cheap. I pulled them off my 00 and replaced them with new ones. They were never bad, no codes, I just put new ones in because I replaced the old cat. Sensors worked fine. I have the up and down stream, they appear factory.
