Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts during inspection.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Use a jack to support the engine slightly.
2. Remove the bolts securing the engine mounts using a socket set.
3. Lift the engine cautiously and remove the old mounts.
4. Install new engine mounts, ensuring correct alignment.
5. Torque bolts to the manufacturer’s specifications (usually around 40-60 ft-lbs, check service manual for exact specifications).

3. Address Ignition System

Sub-steps:
1. Remove the engine cover to access the ignition coils.
2. Disconnect the electrical connectors from each ignition coil.
3. Remove the ignition coils using a socket set and inspect for damage.
4. Replace any faulty coils and ensure that spark plugs are in good working condition; replace if worn.
5. Reconnect the connectors and replace the engine cover.

4. Clean Fuel Injectors

Sub-steps:
1. Remove the fuel rail assembly, following safety precautions to relieve fuel pressure.
2. Use a fuel injector cleaning kit or take injectors to a professional for cleaning.
3. Reinstall cleaned or new injectors and reconnect the fuel rail, ensuring no leaks.

5. Check for Vacuum Leaks

Sub-steps:
1. Inspect all vacuum hoses for cracks or disconnections.
2. Use a smoke machine or carburetor cleaner to identify leaks by observing for changes in engine idle.
3. Replace any damaged hoses and ensure all connections are secure.
