94_yota_pickup

I have a 93 Toyota Pickup 22RE and it has no oxygen sensors on it, I was wondering were the correct place is to put them on ?

You must be getting some great MPG.

I had to unplug mine for about a week before I could get the new one installed and my MPG was awful.

haha, oh yeah, I got AWSOME gas mileage when mine was bad...

ran rich for so long it piped the rich exhaust gases through the EGR valve and into my intake manifold and caused the lovely black goo to build up...

better check for that after throwing your new O2 sensor on if you've been running for a while without it...
