Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge, cleaning supplies.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Error Codes

Connect the OBD-II scanner to the diagnostic port.
Record any trouble codes and research their meanings.
Clear the error codes and perform a test drive to see if they return.

3. Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding area.
Reinstall the air intake duct and ensure all connections are secure.

4. Inspect and Test the Fuel System

Tools Required: Fuel pressure gauge.
Disconnect the fuel pump relay and crank the engine to relieve fuel pressure.
Connect the fuel pressure gauge to the fuel rail and turn the ignition to the "ON" position (do not start).
Check the fuel pressure against manufacturer specifications (typically around 30-50 psi for CR-V).
Replace the fuel filter if pressure is low or if it shows signs of clogging.

5. Check the Air Intake System

Inspect the air filter and replace it if dirty.
Check for any vacuum leaks in the intake manifold and hoses.
Ensure that all connections from the air intake to the throttle body are secure and free from damage.

6. Test Spark Plugs and Ignition Coils

Remove the spark plugs using a socket set.
Inspect the spark plugs for wear, carbon buildup, or damage; replace if necessary.
Use a multimeter to test the ignition coils for proper resistance; replace any faulty coils.

7. Inspect the Mass Airflow Sensor (MAF)

Disconnect the MAF sensor connector.
Remove the MAF sensor and clean it with MAF cleaner.
Reinstall the MAF sensor and reconnect the wiring.
