Solution

1. Preparation

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

2. Clean the Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean any carbon deposits from the throttle plate and bore.
Reassemble the air intake duct securely.

3. Inspect and Replace the Air Filter

Locate and remove the air filter housing.
Check the air filter for dirt and obstructions; replace if necessary with a new, OEM air filter.
Reinstall the air filter housing and ensure it is sealed properly.

4. Check and Replace Spark Plugs (if needed)

Remove the ignition coil cover to access the spark plugs.
Inspect each spark plug for wear or damage; replace with OEM parts if necessary.
Reinstall the ignition coils and cover, ensuring they are seated correctly.

5. Test and Replace Fuel Pump (if necessary)

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "on" position without starting the engine to check fuel pressure; it should match manufacturer specifications.
If pressure is inadequate, replace the fuel pump according to the manufacturer's guidelines.
