Solution

1. Preparation

Gather tools and parts required for repairs.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat surface and securely supported if lifting is necessary.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect for dirt or blockages.
Install a new air filter that meets manufacturer specifications.
Reassemble the air filter housing and ensure it is secured properly.

3. Fuel Pressure Check and Repair

Connect the fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "ON" position (do not start) to check pressure readings.
If pressure is below specifications, inspect and replace the fuel pump if needed.
Replace any clogged fuel filters before the fuel pump if necessary.

4. Ignition System Inspection and Replacement

Remove the ignition coil(s) using a socket set and inspect for cracks or wear.
Replace worn spark plugs, ensuring the gap is set to manufacturer specifications.
Reinstall ignition coils and ensure they are properly seated.

5. Clean Throttle Body

Remove the intake duct to access the throttle body.
Use a throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reassemble the intake duct securely to prevent air leaks.

6. Mass Airflow Sensor Cleaning

Disconnect the MAF sensor connector.
Remove the MAF sensor from the intake system.
Use MAF sensor cleaner to gently clean the sensor elements.
Reinstall the MAF sensor and reconnect the electrical connector.
