ISO professional mechanic for a 1992 Nissan Infiniti m30. The mechanic that just finished working on it said it needed a tune up. I want a professional who can fix it up right, because when it is idling it will skip and turn itself off after a minute of skipping. I do not want this problem anymore. This is the only car I have and I need it cunning at to top shape. Please help me find a mechanic with decent prices that will do me the right way.
