Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.

2. Replace Air Filter

Locate the air filter housing.
Remove the clips or screws holding the air filter in place.
Replace the old air filter with a new one.
Ensure the housing is sealed properly and reassemble.

3. Clean or Replace MAF Sensor

Locate the MAF sensor (usually near the air intake).
Disconnect the electrical connector from the MAF sensor.
Remove the sensor from the intake manifold.
Clean the sensor with MAF cleaner. If damaged, replace with a new sensor.
Reinstall the sensor and reconnect the electrical connector.

4. Inspect and Clean Fuel Injectors

Remove the fuel injectors from the fuel rail.
Use a fuel injector cleaning kit to flush out the injectors.
Reinstall the injectors ensuring they are seated correctly.
Reconnect the fuel rail and check for leaks.

5. Check for Vacuum Leaks

Visually inspect all vacuum hoses for cracks or disconnections.
Use a smoke machine or propane torch (without ignition) to detect leaks.
Replace any damaged hoses or reattach loose connections.
