Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts, typically found on the chassis.
3. Use a socket set to remove the bolts securing the engine mounts.
4. Replace any damaged mounts with new ones.
5. Reinstall the bolts and tighten to manufacturer specifications (usually 30-50 lb-ft).

3. Check and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the ignition coil connectors.
3. Use a socket wrench to remove the spark plugs.
4. Inspect the spark plugs for wear and replace if necessary (recommended gap: 0.040 inches).
5. Reinstall the new spark plugs and reconnect the ignition coils.

4. Inspect Fuel Delivery System

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position without starting the engine and check pressure (should be within manufacturer specs, typically 58-65 psi).
3. If pressure is low, check the fuel filter and replace if clogged.
4. Inspect fuel injectors for proper operation and clean if necessary.
