Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to avoid electrical issues.

2. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket wrench.
Extract the spark plugs using a spark plug socket.
Inspect for wear or fouling; replace with OEM spark plugs if necessary.
Reinstall the spark plugs and ignition coils, ensuring they are properly torqued to manufacturer specifications.

3. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle body interior.
Ensure the throttle plate moves freely without obstruction.
Reattach the air intake duct securely.

4. Check and Repair Vacuum Leaks

Inspect all vacuum lines for cracks or disconnections.
Replace any damaged vacuum hoses or gaskets.
Use a smoke machine if available to detect hard-to-find leaks.

5. Verify Fuel Pressure

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition key to the "On" position without starting the engine to check the pressure.
Compare the reading with manufacturer specifications; if low, investigate further for fuel pump or filter issues.
