Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety during inspection.

2. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover (if applicable) using a socket set.
2. Remove the spark plug wires or ignition coils using a socket wrench.
3. Inspect the spark plugs for damage or excessive wear; replace if necessary.
4. Install new spark plugs, ensuring to set the correct gap according to manufacturer specifications.
5. Reattach ignition coils or spark plug wires.

3. Check Ignition Coils

Sub-steps:
1. Remove the ignition coils as done in the previous step.
2. Test each ignition coil with a multimeter to verify resistance levels.
3. Replace any defective ignition coils with new ones.
4. Reinstall the ignition coils.

4. Fuel Injector Cleaning or Replacement

Sub-steps:
1. Remove the fuel rail to access the fuel injectors.
2. Inspect each fuel injector for clogs or leaks.
3. Clean the injectors using a fuel injector cleaner kit or replace them if damaged.
4. Reinstall the fuel rail ensuring all connections are secure.

5. Inspect Air Intake System

Sub-steps:
1. Visually inspect the air intake hoses for cracks or leaks.
2. Check the air filter for cleanliness and replace if dirty.
3. Ensure the throttle body is clean and free of carbon buildup.
4. Reassemble any components removed during inspection.

6. Engine Compression Test

Sub-steps:
1. Remove spark plugs and disable fuel injection.
2. Attach a compression tester to the first cylinder and crank the engine.
3. Record the reading and repeat for all cylinders.
4. Analyze the results; if compression is low, further investigation into engine internals may be needed.
