Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Clean or Replace the Air Filter

Remove the air filter housing using a socket set.
Inspect the air filter; if dirty, replace it with a new one.
Reinstall the housing and ensure it is secured properly.

3. Fuel System Inspection

Use a fuel pressure gauge to check the fuel pressure at the rail.
If pressure is low, inspect the fuel pump and fuel filter for clogs or failures.
Replace the fuel filter if it shows signs of blockage or if it has not been replaced per the maintenance schedule.

4. Spark Plug Replacement

Remove the ignition coils using a socket set.
Extract the old spark plugs using a spark plug socket.
Inspect for wear and replace with OEM or quality aftermarket plugs.
Reinstall the ignition coils and ensure they are properly seated.

5. Throttle Body Cleaning

Remove the throttle body from the intake manifold using a socket set.
Clean the throttle body with throttle body cleaner and a soft brush to remove carbon buildup.
Reinstall the throttle body, ensuring all gaskets are intact and secure.

6. MAF Sensor Testing and Cleaning

Locate the MAF sensor in the intake system.
Disconnect the MAF sensor connector.
Clean the MAF sensor using MAF cleaner spray; do not touch the sensor with anything.
Reconnect the sensor and ensure it is properly secured.
