Check this link to some good information and a "how to" video on another forum, look at #5 to understand the testing procedure using an ohmmeter.

If the fan comes on when it hits 227 the relay, wiring and fan are all working. Verify the circuit from the ECM is actually grounding the relay when it calls for fan on at 210.
It really is that easy at least in the rear, however the stock bolts only allow for minimal lowering, those who like them lower add longer bolts. Whenever the ride height is changed the alignment should be checked and adjusted.
Your profile says you have a 96 but you are asking for an 86??

Illustration below showing relay location, however if you hear a click the relay is probably working fine. I would remove the wire connector from one of the horns and connect a test light between the green and black wires, if it lights when you press the horn button all is good to that point...
First time I've heard that theory, any evidence to support it? The sirconia style O2 sensor used in nearly all American cars functions by electrochemical process similar to a battery.

You may want to review O2 operation before it is time to recertify, they measure concentration of oxygen, not temperature.:thumb
How Does the Oxygen Sensor Work
As others have pointed out there is only one person to blame here, you came to an open internet forum for free advice then imagine some worldwide conspiracy to take your money. Right or wrong I'm sure any advice offered here was in good faith trying to help you.
Not really any surprise a...
All 4 O2 sensors on your 96 are the same, instead of buying one remove the suspect sensor and swap with a different one, clear the code and see if it returns or moves to the new location. If you get the same code you likely have a bad cat, if it moves replace the sensor.
The two issues may or may not be related, I have had a code 43 in my 93 and it caused no discernible change in the way it ran. I would start with some basics such as checking fuel pressure, also pull the vacuum line off your fuel pressure regulator and inspect it for raw fuel, also do a...
