Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shocks.
Allow the engine to cool before starting work.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar.
Sub-steps:
1. Locate the engine mounts; typically found on the front, rear, and sides of the engine.
2. Use a jack to support the engine gently.
3. Remove the bolts securing the damaged engine mounts using the socket set.
4. Replace with new engine mounts, ensuring correct alignment.
5. Torque bolts to manufacturer specifications (check service manual for specific torque values).

3. Inspect and Replace Spark Plugs

Tools Required: Spark plug socket, ratchet, torque wrench.
Sub-steps:
1. Disconnect ignition coils from the spark plugs.
2. Remove old spark plugs using the spark plug socket.
3. Inspect the condition of the old spark plugs; replace if worn or fouled.
4. Install new spark plugs, applying anti-seize compound if recommended.
5. Torque to manufacturer specifications.

4. Check and Clean the Throttle Body

Tools Required: Throttle body cleaner, soft brush, rags.
Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Spray throttle body cleaner on the throttle body and use a soft brush to remove carbon build-up.
3. Wipe clean with a rag and reassemble the intake duct.

5. Verify Fuel System

Tools Required: Fuel pressure gauge, multimeter.
Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position without starting the engine to check fuel pressure.
3. If pressure is low, inspect the fuel pump and filter for issues and replace if necessary.
