Hey, its very simple, it is located under the engine on one of the exhaust pipes, looks just like O2 sensor. unscrew it with a wrench, unplug it, and replace with a new one, hope it helps.
14.7 is always considered "perfect" AFR, But generally this will change anywhere towards 11-12 when under load(ie boost).
The sensor between the cat and the engine is the air fuel ratio sensor, it looks like an o2 sensor. The o2 sensor is between the cat and the tail pipe. The forward sensor is the af sensor t he rear one is the o2 sensor. Thar answer is for the calif. vehicles. Fed may be different but I dont think the 4 runner had two o2s like some of the sedans. fairly visable tho.
You can buy a kit with new jets and metering rods for this purpose. Quadrajets can be a little tricky, so you might want to get a how-to book and read up on the procedure.
No, an oxygen sensor is not a thermistor sensor. An oxygen sensor measures the amount of oxygen in the exhaust gases of a vehicle to help determine the air-fuel ratio. A thermistor sensor, on the other hand, is a type of temperature sensor that relies on the change in resistance with temperature to measure temperature.
the air fuel ratio is computer controlled dont think there is a way to change it the computer adjust the air/fuel based on sensors and theyre readings. if its not running right its prolly a sensor issue possibly the oxygen sensor

A fraction is a ratio
No, it is not a knock sensor at all. An AF (Air/Fuel Ratio) sensor is also know as a wide range oxygen sensor. It is the newer type oxygen sensor.
It is possible but anytime I have a misfire read on any one cyl. it has been a bad fuel injector. yes it very much can it can throw off your airfuel ratio causing you engine not to fire correctly..
the term for the ratio of vertical change over horizontal change is slope
No, the gear ratio is determined by the number of teeth in the ring gear and pinion gear. To be changed, that would require a physical alteration, which a speed sensor cannot do.
