Solution

1. Preparation

Gather tools and parts needed: OBD-II scanner, socket set, multimeter, replacement air filter, fuel injector cleaner.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Replace Air Filter

Locate the air filter housing, usually near the engine.
Remove the screws or clips securing the housing.
Take out the old air filter and inspect it for dirt and debris.
Install the new air filter, ensuring it fits securely.
Reassemble the air filter housing.

3. Clean Fuel Injectors

Use a fuel injector cleaning kit or fuel system cleaner.
Follow the instructions for the specific product, typically involving adding the cleaner to the fuel tank.
If necessary, remove the fuel injectors for manual cleaning using a specialized cleaning solution and equipment.

4. Inspect and Repair Fuel System

Check all fuel lines and connections for leaks, using a multimeter to test for any electrical issues with the fuel pump.
Replace any damaged hoses or fittings.
If the fuel pump is faulty, remove it from the tank and install a new one according to the manufacturer's specifications.

5. MAF Sensor Cleaning or Replacement

Locate the MAF sensor, usually situated between the air filter and throttle body.
Disconnect the electrical connector and carefully remove the sensor.
Clean the sensor with MAF cleaner. If damaged, replace with a new sensor.
