Something interesting about this subject that others may not know:  Automobiles are very complex machines. The problems and countless. While I and most technicians I know consider to know everything, we do not. That is why I personally have never fixed a vehicle over the phone or internet. I have helped in diagnosis, but not fixed. So please take this into consideration when reading the answers.
