Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery negative terminal to prevent electrical hazards.

2. Inspect and Replace Air Filter

Remove the air filter cover using a socket set.
Take out the air filter and inspect it for dirt and damage.
Replace with a new air filter if it is dirty or damaged.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition key to the "ON" position without starting the engine to check for proper fuel pressure.
If pressure is low, check the fuel pump operation and replace if necessary.

4. Throttle Body Cleaning

Remove the throttle body by loosening the clamps and disconnecting the electrical connector.
Clean the throttle body using throttle body cleaner and a soft cloth.
Reinstall the throttle body and ensure all connections are secure.

5. Ignition System Check

Remove the spark plugs using a socket set.
Inspect the spark plugs for wear and replace any that are worn or fouled.
Check the ignition coils for proper operation and replace if faulty.

6. Final Assembly

Reconnect all components, ensuring all screws and clamps are tightened to manufacturer specifications.
Reconnect the battery negative terminal.
