Solution

1. Preparation

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

2. Inspect and Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the housing.
Remove the old air filter and inspect it for dirt and debris.
Install a new air filter that meets OEM specifications.
Reassemble the air filter housing and secure it.

3. Clean Throttle Body

Locate the throttle body and remove the intake duct.
Use throttle body cleaner and a soft cloth to clean the throttle plate and housing.
Ensure that no cleaner enters the intake manifold.
Reattach the intake duct securely.

4. Check and Replace Fuel Filter

Locate the fuel filter in the fuel line.
Relieve fuel system pressure before removal.
Disconnect the fuel lines from the filter using appropriate wrenches.
Replace the old filter with a new one, ensuring correct orientation.
Reconnect the fuel lines and check for leaks.

5. Inspect and Test MAF Sensor

Disconnect the MAF sensor electrical connector.
Clean the sensor with MAF cleaner to remove dirt and contaminants.
Reconnect the sensor and conduct a test drive to check for improved acceleration.
