Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Inspect and Replace Engine Mounts (if necessary)

Remove components obstructing access to engine mounts.
- Use a socket set to remove any air intake ducts or covers.
Lift the engine slightly.
- Place a jack under the oil pan with a wooden block to avoid damage.
- Raise the engine just enough to relieve pressure on the mounts.
Remove and inspect engine mounts.
- Use a socket and ratchet to unbolt the mounts.
- Check for cracks, tears, or excessive wear.
Install new engine mounts (if applicable).
- Position the new mounts and torque bolts to manufacturer specifications (usually around 50-70 ft-lbs, verify with service manual).
Lower the engine and reassemble components.

3. Clean or Replace Idle Air Control Valve

Locate the IAC valve.
- Refer to the service manual to find specific location details.
Remove the IAC valve.
- Disconnect electrical connectors and unbolt the valve.
Clean the valve.
- Use a throttle body cleaner and a soft cloth to remove carbon deposits.
Reinstall the valve or replace it if damaged.
- Torque bolts to manufacturer specifications.

4. Inspect and Replace Spark Plugs

Remove the ignition coil assembly.
- Disconnect electrical connectors and unbolt the coils.
Remove the spark plugs.
- Use a spark plug socket and ratchet to unscrew the plugs.
Inspect plugs for wear.
- Replace if they show signs of wear or fouling.
Install new spark plugs.
- Torque to specification (usually around 13-15 ft-lbs).
