Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on electrical components.

Tools Required:

OBD-II scanner
Fuel pressure gauge
Socket set
Torque wrench
Screwdriver set

2. Clean or Replace the Air Filter

Remove the air filter housing cover by unscrewing or unclipping it.
Take out the air filter and inspect it for dirt and debris.
If dirty, clean or replace the air filter with a new one. Ensure it fits securely before reassembling the housing.

3. Inspect and Clean the Throttle Body

Locate the throttle body; disconnect the intake duct and any electrical connectors.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
Reconnect the throttle body and intake duct, ensuring all connections are secure.

4. Test and Replace Ignition Components (if necessary)

Remove the ignition coils and inspect them for cracks or damage.
Test the spark plugs for wear; replace if necessary with OEM-equivalent plugs.
Reinstall the ignition coils, ensuring proper torque specifications are followed (typically around 10-15 ft-lbs).

5. Check Fuel System

Connect the fuel pressure gauge to the fuel rail and turn the ignition on (without starting the engine) to check fuel pressure.
If pressure is below specifications, inspect the fuel pump and replace if faulty.
If the fuel filter is clogged, replace it according to the manufacturer's recommendations.
