Solution

1. Preparation

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

2. Replace Air Filter

Locate the air filter housing and release any clips or screws.
Remove the old air filter and inspect for damage.
Install the new air filter, ensuring it is seated properly.
Reassemble the air filter housing.

3. Fuel Pressure Check and Repair

Locate the fuel pressure test port on the fuel rail.
Connect the fuel pressure gauge and turn the ignition to the "ON" position (do not start).
Check if the fuel pressure meets manufacturer specifications.
If pressure is low, inspect the fuel pump and fuel filter for wear.
Replace the fuel pump if necessary.

4. Inspect and Replace Spark Plugs and Ignition Coils

Remove the engine cover if applicable.
Disconnect the ignition coil connectors and remove the coils.
Remove the spark plugs using a socket wrench.
Inspect spark plugs for wear and replace if worn or carbon-fouled.
Install new spark plugs and ignition coils, ensuring proper torque specifications are followed.

5. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
Ensure the throttle plate moves freely.
Reinstall the air intake duct securely.

6. MAF Sensor Check

Disconnect the MAF sensor connector.
Remove the MAF sensor from its housing.
Clean the MAF sensor with MAF cleaner.
Reinstall the sensor and reconnect the electrical connector.
