I recently had my plugs replaced and air filter. However, my mechanic told me that I need a motor mount and a coil pack. Does anyone know what either one of these items and are they important to replace. Also, when it rains water seems to go through my trunk and through the mats and piles up where the spare tre is. Please I really could use some help.

 

The coil pack going bad would either make the car run poorly or set a check engine light.

Now the motor mount is a common problem and can lead to other issues if not repaired.

 

For the water leak have you checked your weatherstripping around the trunk?
