Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, safety glasses, gloves.
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition key to the ON position (do not start the engine) and check the pressure reading.
If the pressure is below specifications (typically 30-50 psi for CR-V), inspect the fuel pump and filter for clogs or failures.

3. Air Intake and Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and housing.
Reinstall the air intake duct securely.

4. Ignition System Check

Tools Required: Socket set, multimeter.
Remove the ignition coils and inspect for cracks or damage.
Measure the resistance of the spark plugs with a multimeter; replace if they are outside the recommended range (typically 0.4-0.6 ohms).
Replace any damaged ignition coils if necessary.

5. Battery and Alternator Test

Tools Required: Multimeter.
With the engine running, check the voltage at the battery terminals; it should read between 13.5-14.5 volts.
If the voltage is below this, check the alternator connections and consider replacing the alternator if faulty.
