Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and the vehicle is parked on a flat surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Remove any components obstructing access to the engine mounts (e.g., air intake or covers).
3. Unbolt the damaged or worn engine mounts using a socket set.
4. Replace with new engine mounts, ensuring they are properly aligned.
5. Torque bolts to the manufacturer's specifications (consult repair manual for exact torque settings).

3. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil connectors and unscrew the coils.
2. Use a spark plug socket to remove the old spark plugs.
3. Check the gap on new spark plugs and adjust if necessary.
4. Install new spark plugs, ensuring they are torqued to the manufacturer’s specifications.
5. Reinstall ignition coils and connectors.

4. Check and Adjust Fuel Pressure

Sub-steps:
1. Locate the fuel rail and attach the fuel pressure gauge.
2. Start the engine and observe the fuel pressure reading; it should meet manufacturer specifications.
3. If pressure is low, inspect the fuel pump and filter for issues.
4. Replace the fuel pump or filter if necessary.

5. Clean Throttle Body

Sub-steps:
1. Remove the air intake duct to access the throttle body.
2. Use throttle body cleaner and a soft brush to clean the throttle body interior.
3. Reassemble the air intake duct securely.
