Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fuel pressure gauge, torque wrench
Disconnect the negative battery terminal to ensure safety during repairs.

2. Address Error Codes

Connect the OBD-II scanner and retrieve any stored error codes.
Clear the codes and take the vehicle for a test drive to see if any codes reappear.

3. Replace Air Filter

Remove the air filter cover using a socket set.
Take out the old air filter and inspect it for dirt and blockages.
Install a new, clean air filter, ensuring it fits snugly in the housing.

4. Inspect and Clean Throttle Body

Remove the intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the bore and plate.
Reinstall the intake duct securely and reconnect any hoses.

5. Test and Replace Spark Plugs

Remove spark plug wires or coils (depending on engine configuration).
Use a socket wrench to remove the old spark plugs.
Inspect plugs for wear; replace with new plugs to manufacturer specifications (check gap size).
Reinstall spark plugs, torque to manufacturer specifications.

6. Check Fuel System

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start) and observe pressure readings.
If pressure is low, consider replacing the fuel pump or filter as necessary.
