Solution

1. Preparation

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

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Inspect the air filter. If dirty or clogged, replace it with a new one.
Reassemble the air filter housing securely.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail's test port.
Start the engine and monitor the pressure; it should meet the manufacturer's specifications.
If pressure is low, check the fuel pump and fuel filter for issues. Replace if necessary.

4. Throttle Body Cleaning

Detach the throttle body by removing the intake duct and electrical connections.
Use throttle body cleaner and a soft cloth to clean the throttle plate and housing.
Reinstall the throttle body and reconnect all electrical connections and ducts.

5. MAF Sensor Testing and Cleaning

Disconnect the MAF sensor electrical connector.
Remove the MAF sensor from the intake duct.
Inspect for dirt or debris and clean with MAF sensor cleaner. Allow it to dry before reinstallation.

6. Transmission Fluid Inspection

Remove the transmission dipstick and check the fluid level and condition.
If low, add the specified type of transmission fluid until it reaches the correct level.
If the fluid is dark or burnt-smelling, consider a transmission fluid change.
