O2 sensors

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.

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