Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety during the inspection.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, fuel pressure gauge.

2. Battery Inspection

Use a multimeter to check the battery voltage; it should read above 12.4 volts.
If the battery is low, charge it fully or replace it if it's faulty.
Reconnect the battery once testing is complete.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail to check for proper pressure (consult manufacturer specifications).
If pressure is low, inspect the fuel pump and filter for clogs or failure and replace as necessary.

4. Spark Plug Replacement

Remove the ignition coils and spark plugs using the socket set.
Inspect the spark plugs for wear or fouling; replace if necessary with OEM specifications.
Torque the new spark plugs to the manufacturer's recommended specifications.

5. Air Intake System Check

Remove the air filter and inspect for dirt or blockages; replace if necessary.
Check the intake hoses for any cracks or loose connections that may cause vacuum leaks.

6. Final Assembly

Reinstall all components in reverse order of removal.
Ensure all connections are secure and that there are no tools left in the engine bay.
