Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to avoid electrical shorts.
Ensure the engine is cool before starting work.

2. Clean or Replace Throttle Body

Tools Required: Throttle body cleaner, screwdrivers, socket set, rags
Remove any air intake ducting connected to the throttle body.
Use throttle body cleaner and a rag to clean any carbon buildup from the throttle plate and surrounding areas.
Reattach the air intake ducting securely.

3. Replace Air Filter

Tools Required: Flat-head screwdriver or socket set (depending on air filter housing)
Open the air filter housing by removing the screws or clips.
Take out the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits snugly in place, and secure the housing.

4. Inspect and Replace Spark Plugs (if necessary)

Tools Required: Spark plug socket, ratchet, torque wrench, gap gauge
Remove the ignition coils by unscrewing them and gently pulling them out.
Use the spark plug socket to remove the spark plugs. Inspect for wear or carbon deposits.
If replacement is needed, install new spark plugs with the correct gap and torque them to the manufacturer's specifications.

5. Test and Replace Accelerator Pedal Position Sensor (if faulty)

Tools Required: Multimeter, socket set
Disconnect the electrical connector from the accelerator pedal position sensor.
Use a multimeter to test the sensor for proper voltage output while pressing the accelerator pedal.
If the readings are out of specifications, replace the sensor with a new one.
