Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Clean or Replace Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Unbolt and detach the throttle body from the intake manifold.
3. Clean the throttle body using throttle body cleaner and a soft brush.
4. Inspect the throttle plate for free movement.
5. Reinstall the throttle body, ensuring proper torque specifications (typically 89 in-lbs).

3. Inspect and Clean MAF Sensor

Sub-steps:
1. Disconnect the MAF sensor connector.
2. Remove the MAF sensor from the air intake system.
3. Use MAF sensor cleaner to clean the sensor element carefully.
4. Allow it to dry completely before reinstalling.

4. Test and Replace Fuel Filter (if necessary)

Sub-steps:
1. Locate the fuel filter within the fuel line.
2. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
3. Disconnect the fuel lines from the filter and replace it with a new one.
4. Reconnect the fuel lines and reinstall the fuse.

5. Check and Replace Accelerator Pedal Position Sensor (if defective)

Sub-steps:
1. Locate the accelerator pedal position sensor on the pedal assembly.
2. Disconnect the electrical connector.
3. Remove the sensor from the assembly.
4. Install the new sensor and reconnect the electrical connector.
