Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Locate the engine mounts (typically near the front and rear of the engine).
2. Use a socket set to remove the bolts securing the mounts to the engine and chassis.
3. Carefully lift the engine with a jack to relieve pressure on the mounts.
4. Remove the old mounts and replace them with new ones, ensuring they are correctly aligned.
5. Torque the bolts to the manufacturer's specifications (usually around 30-50 Nm, consult repair manual).

3. Clean and Test Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Use throttle body cleaner and a soft cloth to clean the throttle plate and interior surfaces.
3. Reinstall the air intake duct ensuring a tight fit.

4. Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the ignition coil connectors and bolts.
2. Extract the ignition coils and inspect for cracks or damage.
3. Using a socket set, remove the old spark plugs.
4. Install new spark plugs, using a torque wrench to tighten to 25 Nm.
5. Reinstall ignition coils ensuring a proper connection.
