Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool down.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, jack stands
Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Locate the engine mounts, typically found at the front and rear of the engine.
3. Use a socket set to remove the bolts securing the mounts.
4. Carefully lift the engine slightly using a jack to relieve pressure on the mounts.
5. Remove the old mounts and install new ones, ensuring they are seated properly.
6. Torque the mount bolts to the manufacturer’s specifications (refer to service manual for exact torque values).

3. Replace Spark Plugs

Tools Required: Spark plug socket, ratchet, torque wrench
Sub-steps:
1. Remove the engine cover if necessary to access the spark plugs.
2. Disconnect the ignition coils from the spark plugs.
3. Remove old spark plugs using a spark plug socket.
4. Check the gap on the new spark plugs and adjust if necessary.
5. Install new spark plugs and torque them to manufacturer specifications.
6. Reconnect the ignition coils.

4. Check and Replace Air Filter

Tools Required: None specifically, but a screwdriver may be needed for the air filter box.
Sub-steps:
1. Locate the air filter housing, usually at the front of the engine bay.
2. Open the air filter housing and remove the old air filter.
3. Inspect the housing for any debris or blockages.
4. Install a new air filter ensuring it fits snugly in the housing.
5. Close the air filter housing securely.

5. Verify Fuel Pressure

Tools Required: Fuel pressure gauge
Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Connect the fuel pressure gauge to the test port.
3. Turn the ignition to the "On" position without starting the engine to check the fuel pressure reading.
4. Compare the reading to the manufacturer’s specifications; replace the fuel pump if pressure is inadequate.
