why does my Toyota Camry XV40 (2007-2011) hesitate when I accelerate?

Solution

1. Preparation

• Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect and Replace Air Filter

• Remove the air filter housing cover using a socket set.
• Take out the old air filter and check for dirt or blockages.
• Install a new air filter, ensuring it fits snugly in place.
• Reattach the housing cover and tighten the screws to the manufacturer’s torque specifications.

3. Clean Throttle Body

• Remove the throttle body by disconnecting the throttle position sensor and the air intake duct.
• Use throttle body cleaner and a clean cloth to remove carbon deposits from the throttle body and plate.
• Reassemble the throttle body and reconnect all components securely.

4. Test and Replace Ignition Components

• Use a multimeter to test the resistance of spark plugs and ignition coils.
• Replace any faulty spark plugs with OEM equivalent, ensuring the correct gap.
• If ignition coils are found to be defective, replace them with new ones.

5. Clean or Replace MAF Sensor

• Disconnect the MAF sensor wiring harness and remove the sensor from the intake.
• Use MAF sensor cleaner to gently clean the sensor wires.
• Reinstall the MAF sensor ensuring it is secure and reconnect the wiring harness.
