Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Engine Mounts

Visually inspect engine mounts for cracks or separation.
Use a pry bar to test for excessive movement in the mounts.
If damaged, proceed to replace engine mounts:
- Sub-steps:
  1. Raise the vehicle securely on jack stands.
  2. Support the engine with a jack.
  3. Remove the bolts securing the damaged engine mount.
  4. Install the new engine mount and torque bolts to manufacturer specifications.

3. Replace Spark Plugs

Remove the ignition coils to access the spark plugs.
Sub-steps:
1. Use a spark plug socket to remove old spark plugs.
2. Check the gap of the new spark plugs and adjust if necessary.
3. Install new spark plugs and reconnect ignition coils.

4. Check Fuel System

Inspect the fuel pressure using a fuel pressure gauge.
Sub-steps:
1. Locate the fuel rail and connect the fuel pressure gauge.
2. Turn the ignition on (do not start the engine) to check pressure.
3. If pressure is low, replace the fuel filter and check the fuel pump function.

5. Examine Air Intake

Check the air filter and intake hose for blockages.
Sub-steps:
1. Remove the air filter and inspect it for dirt and debris.
2. Clean or replace the air filter as necessary.
3. Inspect the intake hose for cracks or loose clamps and replace if needed.
