OP you have been good at describing the play by play of your cars repairs recently. All your cars problems should have been discovered during an inspection that you can pay for in the future. No second guesses, no maybe's just the facts. The diagnostic equipment mechanics have today are precise and answer exactly what's wrong with the car.
Pay for an inspection, take a automotive trouble shooting course, read a book on the subject. Over the time since the thread has been created you probably already have it fixed. Also even if you have replaced the car and your still working from home, take your vehicle onto the interstate once a month and drive the speed limit for an hour it's good for the car.
