Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt or blockage.
Replace with a new air filter if necessary.

3. Check Fuel System

Attach a fuel pressure gauge to the fuel rail’s test port.
Start the engine and observe the pressure reading; it should be within the manufacturer's specifications.
If pressure is low, consider replacing the fuel pump.

4. Inspect Spark Plugs and Ignition Coils

Remove the ignition coil packs using a socket set.
Take out the spark plugs using a spark plug socket.
Inspect for wear and replace them if necessary; gap new plugs according to specifications.

5. Clean Throttle Body

Remove the throttle body from the intake manifold using a socket set.
Clean the throttle body using throttle body cleaner and a soft cloth.
Reinstall the throttle body, ensuring proper torque specifications are followed.

6. Reconnect Battery

Reconnect the negative battery terminal.
Start the engine and let it idle to check for any irregularities.
