Solution

1. Preparation

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

2. Replace Air Filter

Locate the air filter housing.
Open the housing and remove the old air filter.
Install a new air filter ensuring it is seated correctly.
Reassemble the housing.

3. Fuel System Inspection

Attach a fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position (do not start the engine) to check pressure.
If pressure is low, proceed to replace the fuel pump and filter as needed.

4. Throttle Body Cleaning

Remove the air intake duct from the throttle body.
Using throttle body cleaner and a soft cloth, clean the throttle body and the throttle plate.
Reattach the air intake duct securely.

5. Ignition Component Replacement

Remove the ignition coils and inspect them.
Replace any faulty spark plugs and coils with OEM or high-quality aftermarket parts.
Reinstall the ignition components ensuring they are tightened to manufacturer specifications.

6. MAF Sensor Check

Disconnect the MAF sensor connector.
Clean the sensor with MAF cleaner; do not touch the sensor element.
Reconnect the sensor and clear any DTCs from the system.
