Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Ensure 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 both sides of the engine and under the transmission.
- Use a socket set to remove bolts securing the engine mounts.
- Carefully lift the engine slightly to relieve pressure on the mounts.
- Remove the old mounts and replace them with new ones.
- Torque the bolts to the manufacturer’s specifications (usually around 50-60 ft-lbs).

3. Replace Spark Plugs and Ignition Coils

Sub-steps:
- Remove the engine cover if necessary.
- Disconnect the ignition coil connectors and remove the coils using a socket set.
- Remove the spark plugs using a spark plug socket and replace them with new ones.
- Reinstall the ignition coils and reconnect the connectors.

4. Check for Vacuum Leaks

Sub-steps:
- Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
- Replace any damaged hoses.
- Use a vacuum gauge to check for proper vacuum levels at idle.

5. Test Fuel Pressure

Sub-steps:
- Connect a fuel pressure gauge to the fuel rail service port.
- Turn the ignition to the "ON" position without starting the engine and check the fuel pressure reading.
- If the pressure is below specification (typically 40-50 psi), consider replacing the fuel pump or filter.
