Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the engine is cool before beginning work.

2. Address Error Codes

Sub-step 1: Record any error codes retrieved from the OBD-II scanner.
Sub-step 2: Research the error codes to understand their implications; this will guide the subsequent repair steps.

3. Clean or Replace Components

Sub-step 1: If the air filter is dirty, replace it with a new one.
Sub-step 2: For a fouled throttle body, remove it using a socket set, clean it with throttle body cleaner, and reattach.
Sub-step 3: If the MAF sensor is faulty, remove it using a screwdriver, clean it with MAF cleaner, or replace it if necessary.

4. Check and Repair Fuel System

Sub-step 1: Connect a fuel pressure gauge to the fuel rail and check for adequate pressure as specified in the service manual.
Sub-step 2: If pressure is low, inspect the fuel pump and replace if necessary.

5. Reassemble and Test

Sub-step 1: Reconnect any components removed during repairs.
Sub-step 2: Reconnect the negative battery terminal.
Sub-step 3: Start the engine and monitor for any warning lights.
