P0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)

TacoRose's '97 threw this code today. Does this mean I need to replace an O2 sensor?

It means you need to run the diagnostic proceedure listing in the FSM for that code to find out what is wrong and how to fix it.

If you find out that you need an O2 sensor, URD has some kick-ass prices on those if you want to check them out.

To run the diagnostic...is that something on the dealership or a certified Toyota shop can do? Or is there another "toy/tool" I can get to run the diagnostic?

It depends on what the diagnostic requires and your ability. Before you get started you must have the proceedure from the FSM. A good many of the diagnostics can be done with a simple Ohm meter.

Sounds like it might be worth the $$ to take it to the shop.

I cleared the code last night with my reader. I wonder how long before it comes back?
