Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery negative terminal for safety.

2. Inspect and Replace Engine Mounts (if faulty)

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Locate the engine mounts; usually found at the front and rear of the engine block.
3. Use a socket set to remove the bolts securing the engine mounts.
4. Replace worn or damaged engine mounts with new ones.
5. Torque the bolts to the manufacturer's specifications (check service manual for specific values).

3. Clean or Replace the Idle Air Control Valve (if necessary)

Sub-steps:
1. Locate the IAC valve, usually near the throttle body.
2. Disconnect the electrical connector and remove mounting screws with a socket set.
3. Clean the valve and the mounting area with throttle body cleaner.
4. If the valve is damaged or clogged beyond cleaning, replace it with a new unit.

4. Inspect and Replace Spark Plugs (if worn)

Sub-steps:
1. Remove the ignition coil by unscrewing the bolts and disconnecting the electrical connector.
2. Use a spark plug socket to remove old spark plugs.
3. Inspect the spark plugs for wear; replace them if necessary with OEM-spec plugs.
4. Torque new spark plugs to the recommended specifications.

5. Check Fuel Pressure (if low)

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail test port.
2. Start the engine and monitor the fuel pressure reading.
3. If pressure is below specifications, consider replacing the fuel pump or filter.
