Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before proceeding.

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reattach the air intake duct securely.

3. Clean or Replace MAF Sensor

Disconnect the electrical connector from the MAF sensor.
Remove the MAF sensor from the intake manifold.
If dirty, clean the sensor with MAF sensor cleaner. If damaged, replace with a new sensor.
Reinstall the MAF sensor and reconnect the electrical connector.

4. Fuel Pressure Check

Connect a fuel pressure gauge to the fuel rail service port.
Start the engine and observe the pressure reading; it should match the manufacturer specifications (typically around 30-60 psi).
If pressure is low, inspect the fuel pump and fuel filter for issues. Replace if necessary.

5. Inspect Ignition System

Remove spark plugs and inspect for wear or deposits.
Replace any worn spark plugs with new ones according to specifications.
Check ignition coils for proper operation; replace faulty coils as needed.
