Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, cleaning supplies, safety glasses.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before starting any work.

2. Clean the Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body using a socket set.
2. Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
3. Clean the throttle plate and ensure it moves freely.
4. Reattach the air intake duct securely.

3. Inspect and Replace the Idle Air Control Valve

Sub-steps:
1. Locate the idle air control valve (IAC) on the engine.
2. Disconnect the electrical connector and remove the mounting screws using a socket set.
3. Inspect the old valve for carbon buildup and malfunction.
4. Install a new IAC valve (if necessary) and reconnect the electrical connector.
5. Ensure all screws are tightened to manufacturer specifications.

4. Check and Replace Fuel Filter (if applicable)

Sub-steps:
1. Locate the fuel filter in the fuel line (refer to the service manual for location).
2. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
3. Disconnect the fuel lines from the filter, ensuring to have a container to catch any spilled fuel.
4. Replace the old fuel filter with a new one, ensuring correct orientation.
5. Reconnect the fuel lines and install the fuel pump fuse.
