Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Locate the engine mounts (usually found at the front and rear of the engine).
2. Use a socket set to remove the mounting bolts.
3. Carefully lift the engine using an engine hoist or jack to relieve pressure on the mounts.
4. Remove the old engine mounts and replace them with new ones.
5. Torque the mounting bolts to the manufacturer's specifications (typically around 40-50 ft-lbs, verify with service manual).

Tools Required:

Socket set
Engine hoist or jack
Torque wrench

3. Inspect and Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover if necessary.
2. Disconnect the electrical connectors from the ignition coils.
3. Use a socket to remove the ignition coils and spark plugs.
4. Inspect spark plugs for wear; replace if fouled or worn.
5. Install new spark plugs (torque to manufacturer's specifications, usually around 13-16 ft-lbs).
6. Reinstall ignition coils and reconnect electrical connectors.

Tools Required:

Socket set
Torque wrench
Spark plug socket

4. Check Fuel Delivery

Sub-steps:
1. Attach a fuel pressure gauge to the fuel rail.
2. Start the engine and monitor fuel pressure readings.
3. If pressure is below specifications (usually around 50-60 psi), inspect the fuel pump and filter.
4. Replace the fuel pump or filter if necessary.
