It's oxygen sensor. And it shouldn't be too hard. Since you're in Cali, just head out to the junkyard and grab one off a random Toyota. The thing should be held on to the exhaust manifold by two bolts. There is a wire leading out from the sensor to a wiring harness. If you have a socket set, you can do it yourself.

actually it's a 97.... i believe those are heated and a 4 wire.... they range in prices under $100.... depends on if you get it with the factory plug or not.... if you do, then it's more expensive.... but the other route requries you to do the wiring

mine costed 250CDN for mine...OEM ofcourse..... they hardly make aftermarket one for 4 wires....

i went thru 6 Oxygen sensor, 5 of them used /junker/after market, but all failed on me cept for a brand new OEM oxygen sensor.

you decide which to replace with.

well you can get some pretty good bosche ones.... and usually around $100-150 or so you can even get ones that will withstand methanol too....

they switched to the heated 4 wire o2 sensors in the mid/late 90's.... not sure if they were in the ae101/2's but i've heard they were in them later on (which would make sense, as 96 is when obd2 came out and required both the front and rear o2 sensors)
