Good or bad? Should I put used ones in? I live in the south so there's not a lot of rust problems like in the northern states from salt and snow. Thanks all!

If the used are new enough I would say ok. I bought some new Ford front O2s for $55 for both fronts from a guy on Corral that seemed to have plenty of them a while back. Mine were working, but after 125k I figured they could use replacing. I threw away the old ones figuring who would want to do that much work to put in some old ones.

Is it true that it's recommended that the O2's be replaced at 100,000 miles?

Well how hard is it? I looked earlier and I saw them when I looked down on the rear passenger side of the engine....not from underneath so much. Also, After running the bird for a couple hours, and it started rattling/knocking. I checked the oil and the dipstick was searing hot and it was low by about a half quart.

Any thoughts?

Not sure about the oil unless it is running so lean that it is getting hot.

As I remember one of my O2s was a little difficult to get out, but not that bad. You can't use a regular socket because of the wires. There is a special socket with a slot, but I don't think there was enough room to get it on. I am pretty sure I just used an end wrench with another wrench for leverage.

New ones have a thread sealant on it. If you get used ones, you might want to put some thread sealant on there so it doesn't get rusted in.

I ran the car for a minute from cold to warm up the pipes a little. Seems I read that somewhere that they were easier to get out that way.

Will the o2 sensors and EGR valve from a 96/97 fit on a 94/95?

I believe the O2s will work. Seems like the new ones I got were good for many years newer than my 95.

Can't say about the EGR, but since the intakes are different I am thinking no on the EGR.

Both AutoZone and O'Reilly's list different EGR valves and O2 sensors for 1997 and 1994 Thunderbirds.

Rockauto also had different numbers.

I found the ad from the guy I got my 2 new Ford O2 Sensors from. This is what the ad said.
O2 sensors for 4.6 engines, 2 and 4 valve models. These O2's will fit ANY 4 wire application, V8-V6 ect. The plug end MAY require some simple modification to fit in your O2 loom end, it is easy to do with a sharp knife, simply trim off the guide tabs on the end of the O2 plug end. They will work on ANY 4.6 car.

Based on that I think the O2s from a 96 will work.

Is there any recommended brand of O2's to use for a '96 4.6 Tbird? Bosch any good?

I would think that any well-known name-brand would be a good choice!

Their both wrong, I'm using 02's for a 94 on my 97 harness and PCM. They work just fine.
THAT doesn't surprise me! You have NO idea how many times I've been given wrong parts for my '97 Thunderbird! :mad:

Now, if I were to replace my O2's, should I replace the sensors behind the catalysts also?
