Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, cleaning supplies, and a new air filter if necessary.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Addressing Error Codes

Sub-step 1: Connect the OBD-II scanner to the vehicle's diagnostic port.
Sub-step 2: Retrieve and note down any error codes for further analysis.
Sub-step 3: Research the codes to identify potential causes and required repairs.

3. Inspect and Replace Air Filter

Sub-step 1: Open the hood and locate the air filter housing.
Sub-step 2: Remove the screws or clips securing the housing cover.
Sub-step 3: Take out the old air filter and inspect it for dirt or damage.
Sub-step 4: Install a new air filter, ensuring it is seated correctly.
Sub-step 5: Reattach the housing cover and secure it with screws or clips.

4. Clean Throttle Body

Sub-step 1: Disconnect the negative battery terminal to prevent electrical issues.
Sub-step 2: Remove the air intake duct connected to the throttle body.
Sub-step 3: Use throttle body cleaner and a soft cloth to clean the throttle body.
Sub-step 4: Reassemble any removed components and reconnect the battery.

5. Check Fuel Pressure

Sub-step 1: Locate the fuel rail and attach the fuel pressure gauge.
Sub-step 2: Turn the ignition to the "on" position without starting the engine to read the pressure.
Sub-step 3: Compare the pressure reading to the manufacturer's specifications.
Sub-step 4: If the pressure is low, check the fuel pump and filter for issues.
