Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety during electrical work.

2. Inspect and Clean the Throttle Body

Sub-steps:
- Remove the air intake duct from the throttle body.
- Use a throttle body cleaner and a soft cloth to clean the throttle plate and bore.
- Ensure the throttle plate opens and closes smoothly.
Tools Required: Throttle body cleaner, soft cloth, screwdriver set.

3. Test and Replace the Mass Airflow Sensor (if necessary)

Sub-steps:
- Disconnect the electrical connector from the MAF sensor.
- Remove the MAF sensor from the intake duct.
- Use a multimeter to test the sensor's output against manufacturer specifications.
- If faulty, install a new MAF sensor and reconnect the electrical connector.
Tools Required: Multimeter, socket set.

4. Fuel System Inspection and Repair

Sub-steps:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "on" position without starting the engine and check the pressure reading.
- If the pressure is below specifications, check the fuel filter and fuel pump for issues.
- Replace the fuel filter if clogged or the fuel pump if it fails the test.
Tools Required: Fuel pressure gauge, socket set, wrenches.

5. Reassemble and Reconnect

Sub-steps:
- Reattach the air intake duct and any components removed during inspection.
- Reconnect the battery.
- Ensure all connections are secure and components are properly installed.
