Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Addressing the Air Filter

Remove the air intake duct using a socket set.
Take out the air filter and inspect for dirt or blockage.
Replace with a new air filter if necessary.
Reattach the air intake duct securely.

3. Throttle Body Cleaning

Locate the throttle body and remove the intake hose.
Use throttle body cleaner and a clean rag to remove carbon buildup from the throttle plate.
Open the throttle plate manually to access all areas.
Reinstall the intake hose and ensure all connections are tight.

4. Fuel System Inspection

Attach the fuel pressure gauge to the fuel rail.
Turn the ignition to the "on" position without starting the engine and check the pressure reading.
If pressure is below specifications, inspect the fuel pump and replace if necessary.
Remove the fuel pressure gauge after testing and reconnect any lines or components.

5. Ignition System Check

Remove the spark plugs using a socket set and inspect for wear.
Replace any worn or damaged spark plugs with OEM parts.
Test ignition coils for proper function using a multimeter; replace if faulty.

6. Vacuum Leak Detection

Inspect all vacuum lines for cracks or disconnections.
Use a smoke machine or carburetor cleaner to check for leaks while the engine is running.
Replace any damaged hoses and recheck idle and performance.
