Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle’s battery to prevent electrical issues during repairs.
Allow the engine to cool down if it has been running.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, engine hoist or jack.
Steps:
1. Lift the front of the vehicle using a jack and secure with jack stands.
2. Locate the engine mounts and inspect for any visible damage.
3. If damaged, support the engine with an engine hoist or jack.
4. Remove the bolts securing the old engine mounts using a socket set.
5. Position the new engine mounts and secure them with bolts, tightening to the manufacturer’s torque specifications.

3. Check and Replace Spark Plugs

Tools Required: Socket set, torque wrench, gap gauge.
Steps:
1. Locate the spark plugs and remove the ignition wires.
2. Use a socket set to remove the old spark plugs.
3. Check the gap on the new spark plugs and adjust if necessary using a gap gauge.
4. Install the new spark plugs and tighten to the specified torque.
5. Reconnect the ignition wires.

4. Fuel System Inspection and Repair

Tools Required: Fuel pressure gauge, wrench set.
Steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Start the engine and check for proper fuel pressure; it should match the manufacturer's specifications.
3. If pressure is low, inspect the fuel filter and fuel pump for issues.
4. Replace any faulty components as necessary.
