Hello, There is a common problem with the PCV valve (https://www.yourmechanic.com/services/pcv-valve-hose-replacement) allowing oil to enter into the intake and burn oil on these cars. There is a modified PCV valve that has been made to prevent this from happening. I...

Unfortunately, I don't have the wiring diagram for this vehicle handy. However, my guess is that the clockspring somehow got damaged. If your SRS (airbag) warning light is also on, this is even more of an indication the clockspring requires...
