Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Remove any components obstructing access to engine mounts (e.g., covers or brackets).
2. Visually inspect engine mounts for cracks, tears, or deformation.
3. If damaged, remove the bolts securing the engine mounts using a socket set.
4. Replace with new engine mounts, ensuring proper alignment.
5. Torque the bolts to the manufacturer's specifications (typically around 40-50 ft-lbs).

3. Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the ignition coil connectors and bolts.
2. Extract the ignition coils and inspect for damage.
3. Replace spark plugs with OEM or equivalent parts, ensuring correct gap (typically 0.044 inches).
4. Reinstall the ignition coils and secure them with bolts.

4. Clean Fuel Injectors

Sub-steps:
1. Remove fuel injector rail by detaching the clips and bolts.
2. Carefully extract the fuel injectors.
3. Clean the injectors using a fuel injector cleaning kit or solvent.
4. Reinstall injectors with new O-rings to prevent leaks.
5. Reattach the fuel injector rail and ensure all connections are secure.

5. Check for Vacuum Leaks

Sub-steps:
1. Inspect all vacuum hoses for cracks or disconnections.
2. Use a smoke machine or propane to detect leaks.
3. Replace any damaged hoses or fittings.
4. Clear any DTCs from the OBD-II scanner after repairs.
