why does my Toyota RAV4 hesitate during acceleration

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Allow the engine to cool if it has been running.

2. Inspect and Replace Spark Plugs

• Remove the ignition coil cover using a socket set.
• Remove the ignition coils from the spark plugs.
• Use a spark plug socket to remove the spark plugs.
• Inspect spark plugs for wear; replace if necessary with OEM specifications (typically NGK or Denso brands).
• Install new spark plugs and torque them to manufacturer specifications (usually around 13-15 ft-lbs).

3. Clean Throttle Body

• Remove the air intake duct connected to the throttle body.
• Use throttle body cleaner and a soft cloth to clean any carbon buildup inside the throttle body.
• Reinstall the air intake duct securely.

4. Check and Replace Fuel Filter

• Locate the fuel filter and inspect it for clogs.
• If necessary, remove the old fuel filter using a wrench, ensuring to relieve fuel pressure first.
• Install a new fuel filter in the correct orientation and tighten connections.

5. Inspect Fuel Injectors

• Remove the fuel injector connectors carefully.
• Use a multimeter to check the resistance of each injector; replace if out of specifications.
• Clean fuel injectors using a fuel injector cleaning kit if they appear dirty.
