Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery negative terminal to ensure safety.

2. Address Ignition System

Remove Engine Cover:
- Use a socket set to remove any bolts securing the engine cover.
- Carefully lift off the cover to access ignition components.
Inspect and Replace Spark Plugs:
- Remove the ignition coils by unbolting them and disconnecting the electrical connectors.
- Unscrew the spark plugs using a spark plug socket.
- Inspect spark plugs for wear or damage; replace with OEM-spec plugs if necessary (torque to manufacturer specifications).
Examine Ignition Coils:
- Check for cracks or damage on ignition coils.
- Test each coil's resistance with a multimeter; replace any faulty coils.

3. Check Fuel System

Inspect Fuel Injectors:
- Remove the fuel rail (if necessary) to access the injectors.
- Check for leaks, clogs, or damage; clean or replace as needed.
Test Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition on (but do not start the engine) to check pressure; compare to manufacturer specifications.
Replace Fuel Filter (if applicable):
- Locate the fuel filter and use a wrench to disconnect the lines.
- Replace with a new filter and ensure correct orientation.

4. Inspect Intake System

Check for Vacuum Leaks:
- Inspect all vacuum hoses for cracks or disconnections.
- Use a smoke machine or carburetor cleaner to identify leaks.
Clean Throttle Body:
- Remove the throttle body and clean it using throttle body cleaner.
- Reinstall the throttle body and reconnect any hoses.

5. Compression Test

Perform Compression Test:
- Remove spark plugs and insert a compression gauge into each cylinder.
- Crank the engine and record the pressure readings; compare to manufacturer specifications.
Identify Any Low Compression Issues:
- If compression is low in any cylinder, further investigation is needed (potential head gasket failure, piston ring wear).
