Solution

1. Preparation

Gather tools and parts needed for repairs.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety.

2. Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if present.
2. Disconnect the ignition coil connectors.
3. Unscrew the ignition coils and remove them.
4. Use a socket wrench to remove old spark plugs.
5. Install new spark plugs to the specified torque (typically 13-15 lb-ft).
6. Reinstall ignition coils and reconnect the connectors.

3. Inspect and Replace Ignition Coils (if necessary)

Sub-steps:
1. Test each ignition coil with a multimeter for resistance.
2. Replace any faulty ignition coils with new ones, ensuring proper alignment.
3. Reconnect the electrical connectors.

4. Clean or Replace Fuel Injectors

Sub-steps:
1. Remove the fuel rail as per manufacturer guidelines.
2. Inspect fuel injectors for clogs; clean with a fuel injector cleaning kit or replace if necessary.
3. Reinstall the fuel rail and ensure it is secured properly.

5. Check for Vacuum Leaks

Sub-steps:
1. Visually inspect all vacuum hoses for cracks or disconnections.
2. Use a smoke machine to detect any hidden leaks, if available.
3. Replace any damaged hoses.

6. Compression Test

Sub-steps:
1. Remove spark plugs to access cylinder chambers.
2. Connect a compression gauge to the first cylinder and crank the engine.
3. Record the compression readings and repeat for all cylinders.
4. Compare readings to manufacturer's specifications; replace engine components if compression is low.
