Solution

1. Preparation

Gather tools and parts needed for repairs.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Replace Worn Engine Mounts

Sub-steps:
1. Locate the engine mounts under the vehicle.
2. Use a socket set to remove the bolts securing the mounts to the engine block and chassis.
3. Carefully lift the engine slightly using a jack to relieve pressure on the mounts.
4. Replace the worn mounts with new ones, ensuring proper alignment.
5. Torque the bolts to manufacturer specifications (refer to service manual for specific torque values).

3. Clean Throttle Body and Idle Air Control Valve

Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Use throttle body cleaner and a soft brush to clean the throttle body and IAC valve.
3. Ensure all carbon deposits are removed and the components are free of obstruction.
4. Reassemble the air intake duct and reconnect any hoses.

4. Replace Spark Plugs and Ignition Coils (if necessary)

Sub-steps:
1. Remove the ignition coil connectors and unscrew the coils from the engine.
2. Replace old spark plugs with new ones, ensuring correct gap settings.
3. Reinstall the ignition coils and securely connect the electrical connectors.
