Pressure test the car for leaks.

Inspect the fluid

Fluid is always cheaper than a transmission.

No, get an alternator even if you have to source a junkyard one.

Make sure the alternator/battery cables are in good shape.

The tire came off because the lower ball joint failed, you need to do suspension work on this car sadly.

You have a bad alternator or an issue with the ground.

Replace the pcv valve and use 5w-30 oil. The vcm system is usually what causes issues on this car. Also be sure to service the transmission and make sure you keep up on the timing belt service as well, otherwise it’s a good car.
