Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is cool before starting work.

2. Inspect and Replace Engine Mounts

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Locate the engine mounts (typically found on the front and rear of the engine).
- Visually inspect for cracks or excessive wear.
- Using a socket set, remove the bolts securing the damaged mounts.
- Install new engine mounts, ensuring they are aligned properly.
- Torque bolts to manufacturer specifications (consult repair manual for specific torque values).

3. Check and Repair Vacuum Leaks

Sub-steps:
- Start the engine and listen for hissing sounds that indicate a vacuum leak.
- Use a smoke machine or carb cleaner to identify leak sources.
- Replace any damaged vacuum hoses and ensure all connections are tight.

4. Inspect and Replace Spark Plugs & Ignition Coils

Sub-steps:
- Disconnect the negative battery terminal.
- Remove the engine cover (if applicable) to access the ignition coils.
- Unplug the ignition coils and remove them using a socket set.
- Extract spark plugs using a spark plug socket; inspect for wear or deposits.
- Install new spark plugs and ignition coils, ensuring they are properly torqued.

5. Fuel System Inspection

Sub-steps:
- Attach a fuel pressure gauge to the fuel rail.
- Turn the ignition key to the "On" position (do not start) and check the fuel pressure against specifications.
- If pressure is low, inspect the fuel pump and filter, replacing them if necessary.
