Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, cleaning solvent, throttle body cleaner, rags.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body by loosening the clamps and disconnecting any sensors.
2. With a throttle body cleaner and a clean rag, gently clean the throttle plate and surrounding area to remove any carbon buildup.
3. Ensure the throttle plate moves freely and is not obstructed.
4. Reconnect the air intake duct, ensuring a secure fit.

3. Test Throttle Position Sensor

Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to monitor the throttle position sensor readings while manually pressing the accelerator pedal.
3. If readings are erratic or the sensor is malfunctioning, replace the throttle position sensor.

4. Inspect Throttle Cable/Linkage (if applicable)

Sub-steps:
1. Examine the throttle cable for any fraying, kinks, or binding points.
2. If necessary, replace the throttle cable.
3. Ensure that the throttle linkage moves freely without any binding.

5. Final Assembly and Testing

Sub-steps:
1. Recheck all connections and ensure everything is secure.
2. Start the engine and allow it to idle, monitoring for any unusual behavior.
3. Test drive the vehicle to ensure smooth acceleration and throttle response.
