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 electrical shorts.

2. Inspect and Replace Engine Mounts

Sub-steps:
- Raise the vehicle safely using jack stands.
- Locate the engine mounts, typically found at the front, rear, and sides of the engine.
- Visually inspect each mount for cracks, tears, or fluid leaks.
- If damaged, remove the bolts securing the engine mount to the engine and chassis using a socket set.
- Replace with new engine mounts, ensuring proper alignment.
- Torque bolts to manufacturer specifications (typically around 30-40 Nm, verify with a service manual).

3. Replace Spark Plugs and Ignition Coils

Sub-steps:
- Remove the engine cover if applicable.
- Disconnect the ignition coil connectors and remove the coils using a socket set.
- Remove the spark plugs using a spark plug socket.
- Inspect plugs for wear; replace with OEM or equivalent plugs, ensuring correct gap specifications.
- Reinstall ignition coils, ensuring they are seated properly and reconnect the connectors.

4. Check Fuel System

Sub-steps:
- Connect a fuel pressure gauge to the fuel rail.
- Start the engine and monitor fuel pressure; it should be within manufacturer specifications (typically around 3.0-3.5 bar).
- If pressure is low, inspect the fuel pump and filter for blockages; replace as necessary.

5. Inspect for Vacuum Leaks

Sub-steps:
- Start the engine and use a smoke machine or propane torch (without flame) around vacuum lines and the intake manifold.
- Listen for changes in engine idle indicating a vacuum leak.
- Replace any damaged hoses or gaskets found during inspection.
