Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Use a jack to support the engine slightly.
2. Remove the bolts securing the engine mounts to the engine and chassis using a socket set.
3. Inspect the mounts for cracks or deterioration.
4. Replace with new engine mounts if damaged.
5. Reinstall bolts and tighten to manufacturer specifications (typically around 25-30 Nm).

3. Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Disconnect the battery to prevent electrical shorts.
2. Remove the engine cover if applicable.
3. Disconnect the ignition coils and remove them using a socket set.
4. Unscrew and remove the old spark plugs using a spark plug socket.
5. Install new spark plugs to the specified torque (usually 20-30 Nm) and reconnect ignition coils.

4. Clean Idle Air Control Valve (IACV)

Sub-steps:
1. Locate the IACV, typically near the throttle body.
2. Disconnect the electrical connector and remove the mounting screws.
3. Clean the IACV with throttle body cleaner to remove carbon deposits.
4. Reinstall the IACV and reconnect the electrical connector.
