Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before starting work.

2. Replace Air Filter

Locate the air filter housing.
Open the housing by releasing clips or screws.
Remove the old air filter and inspect for dirt and blockages.
Install a new air filter, ensuring it fits snugly.
Reassemble the housing and secure it.

3. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding area.
Wipe away any residue with a clean cloth.
Reattach the intake duct securely.

4. Test and Replace Fuel Pump (if necessary)

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the ON position (do not start) and check the pressure reading against specifications (typically around 30-50 psi for CR-V).
If pressure is low, access the fuel pump in the fuel tank and replace it.
Disconnect fuel lines and electrical connectors carefully.
Remove the fuel pump assembly and install the new pump, ensuring proper sealing.

5. Check and Replace Transmission Fluid (if necessary)

Locate the transmission dipstick and check the fluid level.
If low or dirty, drain the transmission fluid using a drain pan.
Replace with new transmission fluid that meets Honda specifications (typically Honda ATF DW-1).
Refill to the appropriate level and check for leaks.
