I would take it to the dealer immediately, as it sounds like the traction control is spontaneously being activated

You can check the trouble codes (DTCs) with a code reader and go from there, but unless you have the necessary repair skills, you should leave it to a dealer or reputable repair shop.

Given the age of the vehicle, it will be difficult to find a service manual, but that's what you need. You can also try Alldatadiy.com.

I039 is a road sensing suspension problem, I042 is battery voltage too high. I would first try to clear the codes and try to figure out why the voltage is too high - often a faulty regulator in the generator.
You also seem to have a battery drain problem - something besides the keep-alive circuit is drawing it down. First check all lights (including trunk and under hood) and the rear air compressor when the car is turned off.
Road sensing problem could because of the high voltage, but could also be one of the height sensors at each wheel is detached or broken, or the RSS module has given up the ghost.

Although the fault may be in the mirror itself (like a switch), wiring and connector is above the headliner, and that is what you need to check.

not many engines have a low oil sensor so it is up to the driver to keep an eye on the oil light or check the level at least every other day
if you get a socket onto the harmonic balancer nut and try to turn it , that will indicate if the motor has seized or not
clicking starter solenoids indicate loose battery terminals , dirty terminals bad ground wire connections bad battery ( load test will check that)

As the prescribed method isn't working it would seem likely the antitheft system is broken and should be checked by a professional.

Electronics aren't bulletproof and at over 20 years old the ones fitted to your car are 20 years less robust and 20 years less sophisticated and easily damaged by such things as welding, battery charging, jump starting or even nearby lightning strikes. Such instances often do not cause obvious damage immediately but rather have a weakening effect so the final breakdown happens later, maybe years later.

Any DTC codes?
It is a very bad idea to use a lot of fuel injector cleaner - you will ruin your injectors.
Is the oil loss through the engine or on the floor? How about oil in the antifreeze?
This engine has two crank sensors - when one fails, the engine will usually run rough - you can't check them, so change them both.
Did you check the traction control system? Is it always on?
A faulty EGR valve and/or TPS sensor can also often cause your misfire and power problems.
And lastly the EVAP system is tricky on these vehicles - check the vent valves and hoses.
There really is no end of things that can cause these problems.

This may be related to the antitheft system The system is known for turning off the starter and/or injectors when it fails. Normally when the injectors are turned off, the car will run for a second or two, and then stall. Is there a light on the dash that says SECURITY or a picture of a car with a lock through it? This is a common problem worth looking into. http://www.diy-gm-security.com/

Take it to your mechanic and ask him. There are so many things that could happen that only a mechanic can help. if its going to cost too much to fix fill your tank and keep track of the mileage so when you go so many miles you know its time to fill up.
