Solution

1. Preparation

Tools Needed: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge.
Safety Warning: Disconnect the battery before working on electrical systems.

2. Address Engine Mounts

Locate Engine Mounts: Identify and access the engine mounts under the vehicle.
Inspect Condition: Check for cracks, tears, or excessive movement in the mounts.
Replace if Necessary: If damaged, remove the old mounts using a socket set, and install new mounts, tightening to manufacturer specifications.

3. Clean or Replace Idle Air Control Valve

Remove the Valve: Disconnect the electrical connector and remove the idle air control valve from the throttle body.
Clean the Valve: Use a throttle body cleaner to remove carbon deposits. If cleaning is ineffective, replace the valve with a new one.
Reinstall the Valve: Secure the valve back in place and reconnect the electrical connector.

4. Inspect and Replace Spark Plugs

Remove Ignition Coils: Disconnect and remove the ignition coils from the spark plugs using a socket set.
Check Spark Plugs: Inspect the condition of the spark plugs for wear or fouling.
Replace as Needed: Replace any worn or damaged spark plugs, ensuring they are gapped correctly per manufacturer specifications.

5. Check Fuel Injectors

Access Fuel Injectors: Remove necessary engine components to access the fuel injectors.
Test Injectors: Use a multimeter to test the injectors for proper resistance and operation.
Clean or Replace: Clean the injectors using a fuel injector cleaner or replace them if faulty.
