Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent any electrical issues during repairs.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, jack and jack stands.
Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts; typically found at the front and rear of the engine.
3. Inspect each mount for cracks, tears, or fluid leaks.
4. If damaged, remove the bolts securing the mount to the engine and chassis.
5. Replace with new engine mounts, ensuring they are properly aligned.
6. Torque the bolts to manufacturer specifications.

3. Inspect Spark Plugs

Tools Required: Socket set, spark plug socket, torque wrench.
Sub-steps:
1. Remove the ignition coils or spark plug wires as applicable.
2. Remove the spark plugs using the spark plug socket.
3. Inspect each spark plug for signs of wear or fouling.
4. Replace any faulty spark plugs with new ones, ensuring correct gap settings.
5. Reinstall the spark plugs and reattach the ignition coils or wires.

4. Check Fuel Delivery System

Tools Required: Fuel pressure gauge, basic hand tools.
Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail test port.
2. Turn the ignition to the "ON" position (do not start the engine) and record the fuel pressure.
3. Compare the reading with manufacturer specifications; replace the fuel filter or pump if pressure is low.
4. Inspect fuel injectors for proper function and replace if necessary.
