Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, multimeter.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool down before starting work.

2. Inspect and Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the housing cover.
Take out the old air filter and inspect for dirt or damage.
Replace with a new air filter (OEM recommended).
Reassemble the air filter housing securely.

3. Test and Replace Fuel Pump (if necessary)

Connect a fuel pressure gauge to the fuel rail.
Start the engine and observe the fuel pressure reading; it should be within manufacturer specifications (typically around 30-50 psi).
If pressure is low, inspect the fuel pump relay and wiring.
If the pump is faulty, disconnect fuel lines and electrical connectors, then remove the pump from the fuel tank.
Install a new fuel pump, reconnect lines and connectors, ensuring no leaks.

4. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean carbon deposits.
Open the throttle plate manually and clean inside thoroughly.
Reattach the duct and ensure clamps are secure.

5. Inspect and Replace Spark Plugs

Remove the coil packs by unscrewing them from the cylinder head.
Extract the old spark plugs using a spark plug socket.
Inspect the old plugs for wear; replace them with new ones if needed (OEM recommended).
Torque new spark plugs to the manufacturer’s specifications (usually around 13-15 ft-lbs).
