I recently had my car repaired, it was sitting for a few years with little or no use. When I drove it home from the shop I noticed the car is much louder sounding from the interior, and that the car vibrates rather rough. The sound and vibrations are prevalent at idle and under power. Neither of which were issues before the car had sat unused. There is now a check engine light on after a few around the block runs.
Any ideas?
