It helps to have tiny hands but you should be able to do it. The size of the wrench you'll need is 17 mm and a crow foot socket or flare wrench can be handy.
Do I need a mechanic to install the O2 sensors on a 97 Discovery? Or is it something that I can do myself since I'm pretty handy? Thanks guys...
Read though this, and keep in mind that you need to remove the coil pack to get to the connectors as they are ontop of the bell housing, you can see them, but you cannot reach them from the top or bottom, remove the coils and you can now reach them.
The coils are held on by 4 nuts.
I just removed mine the other day without removing the coil packs.
The left one I was able to remove from above.
The right one I used a long flat blade screw driver to slide if off the bracket. I then flattened the end of a wire coat hanger, bent it at a 180 (about 1" long) and hooked it in the slot of the connector where it slides on to the bracket, then wrapped the other end around something (I think the charcoal canister bracket) to hold it in place then reached up from below the transmission, squeezed the other connector release and pulled it off.
I haven't looked at the coil pack so it may be easier to remove it.

Thanks for the quick response. I think I'll just have someone else do it. LOL! The guy is charging me $500 for all 4 of them. Reasonable? You guys happen to know anyone here in Los Angeles who can do the job for me? Thanks again...

Book time is about 1 1/2 hours for all 4. Sensors can be bought for about $60-$65 each. You do the math.

Okay, okay, I'll do the math...
$260 for sensors(at $65 each) and $150 for labor(at $100/hr) comes to $410. Now there will be a markup for parts, additional fees, such as hazardous materials and shop supplies(usually around $10-15).
So it sounds like a reasonable price from a shop, but not a reasonably price to me when you could do it yourself.

You only need the front 2 replaced, they are the ones that control the fuel mix, the rears only tell the ECU if the cats are working or not, so unless you have codes for the rears leave them alone, and then those you can do yourself, the plugs for those are not hidden.
The fronts and rears use the exact same sensor, so save your old ones to use on the back if/when they go bad.
