Solution

1. Preparation

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

2. Clean the Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and inside of the throttle body.
Reattach the air intake duct securely.

3. Check and Replace the Fuel Filter

Locate the fuel filter (usually under the vehicle or near the fuel tank).
Use a fuel line disconnect tool to relieve pressure and disconnect the fuel lines.
Remove the old fuel filter and install the new one, ensuring the correct orientation.
Reconnect the fuel lines and check for leaks.

4. Inspect and Test the Mass Airflow Sensor

Disconnect the electrical connector from the MAF sensor.
Remove the sensor from the intake manifold.
Clean the sensor with MAF cleaner and reinstall it.
Reconnect the electrical connector.

5. Transmission Fluid Check

Start the engine and let it warm up to operating temperature.
With the engine running, check the transmission fluid level using the dipstick (if applicable).
If low, add the manufacturer-recommended transmission fluid as needed.

6. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a minute.
Test drive the vehicle to verify that the acceleration delay has been resolved.
