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 to ensure safety.

2. Inspect Engine Mounts

Use a socket set to remove any covers obstructing engine mounts.
Visually inspect the engine mounts for cracks or separation.
Replace any damaged mounts with new ones, ensuring they are torqued to factory specifications.

3. Replace Spark Plugs

Remove the ignition coils using a socket set.
Take out the spark plugs with a spark plug socket.
Inspect the spark plugs for wear; replace them with OEM parts if necessary.
Reinstall the spark plugs and ignition coils, ensuring proper torque.

4. Clean or Replace Fuel Injectors

Remove the fuel rail using appropriate tools.
Inspect fuel injectors for clogs; clean them with a fuel injector cleaner or replace them if heavily fouled.
Reinstall the fuel rail, ensuring that all connections are secure.

5. Test and Clean Idle Air Control Valve

Locate the IAC valve, typically mounted on the throttle body.
Remove the IAC valve and inspect it for carbon buildup; clean it with throttle body cleaner.
Reinstall the IAC valve and reconnect any electrical connectors.
