Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar, jack stands
Sub-steps:
1. Use a jack to support the engine slightly; do not lift it.
2. Remove the bolts securing the engine mount to the engine and frame.
3. Carefully lift the mount out and check for cracks, separation, or excessive wear.
4. Replace with a new engine mount if necessary, ensuring it aligns with factory specifications.
5. Torque the mount bolts to manufacturer specifications.

3. Check and Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench
Sub-steps:
1. Remove the ignition coil covers if present.
2. Disconnect the ignition coils and remove them using a socket.
3. Extract the spark plugs using a spark plug socket.
4. Inspect for wear or damage; replace with OEM spark plugs if necessary, ensuring proper gap.
5. Reinstall ignition coils and covers, torquing to specifications.

4. Clean or Replace Fuel Injectors

Tools Required: Fuel injector cleaning kit, socket set
Sub-steps:
1. Relieve fuel pressure from the fuel system by removing the fuel pump fuse and starting the vehicle until it stalls.
2. Disconnect the fuel injectors and remove them from the fuel rail.
