Solution

1. Preparation

Gather tools and parts required for repairs.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shock.

2. Replace Worn Engine Mounts

Sub-steps:
1. Locate the engine mounts (usually one on the front, rear, and sides).
2. Use a socket set to remove the bolts securing the damaged engine mount.
3. Lift the engine slightly with a jack and remove the old mount.
4. Install the new engine mount, ensuring it is aligned properly.
5. Torque the bolts to the manufacturer’s specifications (usually around 50-70 ft-lbs).

3. Clean Throttle Body

Sub-steps:
1. Remove the intake duct connected to the throttle body using a screwdriver.
2. Spray throttle body cleaner onto a clean rag and wipe the interior of the throttle body.
3. Ensure the throttle plate opens and closes smoothly.
4. Reattach the intake duct securely.

4. Inspect and Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the electrical connectors from the ignition coils.
3. Remove the bolts holding the ignition coils and take them out.
4. Unscrew the old spark plugs using a spark plug socket.
5. Install new spark plugs, hand-tightening, then torque to the manufacturer’s specifications (typically around 13-16 ft-lbs).
6. Reinstall ignition coils and reconnect electrical connectors.
