Without the O2, the engine will run rich all the time and you're burning gas like crazy. If it can bolt into the exhaust and plug into the harness, you can use it.

I don't think you can.

AFAIK - Toyota swapped to more accurate o2 sensors with OBD-II cars. They threw out the $20 one wire ones.

Get on ebay and do a search. You can find them new for like $20-35 usd.
