Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, cleaning supplies (throttle body cleaner).
Ensure the vehicle is parked on a level surface, the engine is cool, and the battery is disconnected for safety.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve and document any error codes. Clear the codes if necessary.
If codes related to the fuel or ignition system are present, proceed with their respective diagnostics.

3. Inspect Air Intake System

Remove the air filter and inspect it for dirt or blockages; replace if necessary.
Examine the intake hose for cracks or loose connections. Replace any damaged components.
Clean the throttle body using throttle body cleaner and a soft cloth. Ensure no excess cleaner enters the intake.

4. Check Fuel System

Attach the fuel pressure gauge to the fuel rail and turn the ignition to the "ON" position (do not start the engine) to check the pressure.
If the pressure is below specification, check the fuel pump and fuel filter for issues.
Replace the fuel filter if it's clogged or the fuel pump if it fails to meet pressure requirements.

5. Inspect Ignition System

Remove spark plugs and inspect them for signs of wear or fouling; replace if necessary.
Test ignition coils for proper operation using a multimeter, ensuring they meet resistance specifications.
Reinstall or replace any defective components.

6. Reassemble and Test

Reconnect all components securely, ensuring no loose connections remain.
Reconnect the vehicle battery and start the engine to ensure it runs smoothly.
