Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Ensure the vehicle is on a flat surface and securely supported.

2. Inspect and Replace Engine Mounts (if necessary)

Sub-steps:
1. Locate the engine mounts and visually inspect them for cracks or excessive wear.
2. If damaged, use a socket set to unbolt and remove the mounts.
3. Install new engine mounts by aligning them with the mounting points and tightening to manufacturer specifications (usually around 40-60 Nm).

3. Clean or Replace Spark Plugs and Coils

Sub-steps:
1. Remove the ignition coils using a socket wrench.
2. Inspect spark plugs for wear; replace with OEM plugs if worn (torque to manufacturer specifications).
3. Reinstall ignition coils and ensure they are secured properly.

4. Check and Clean the Idle Air Control Valve

Sub-steps:
1. Locate the idle air control valve (IAC) and remove it using a socket set.
2. Clean the valve and its mounting surface with throttle body cleaner.
3. Reinstall the IAC and ensure all connections are secure.

5. Inspect and Test Fuel Injectors

Sub-steps:
1. Disconnect the fuel injector connectors and remove them from the engine.
2. Use a fuel pressure gauge to check for proper injector operation.
3. Clean or replace clogged injectors as needed before reinstallation.
