After telling my dad it was a part that needed to be changed and him paying to get it changed, the same problem happened again with his car. So he took it back and they fixed something else for another 350 bucks... Seems like this problem should have been diagnosed originally. He spent over 600 on a part that should have only coated 350... This trumps my original post. You can be the friendliest person in the world if a error is made that makes me pay extra money my trust will go down. We've started using another shop since this experience.
