why does my Ford Mustang S650 (2024-Present) check engine light come on during acceleration

Solution

1. Preparation

• Gather tools and parts required for repair.
• Disconnect the battery negative terminal to prevent electrical issues during repairs.

2. Address Diagnostic Trouble Codes (if applicable)

• If DTCs indicate a specific problem (e.g., P0300 for misfires), proceed to repair or replace the affected components based on the specific code.

3. Inspect and Clean MAF Sensor

• Remove the MAF sensor from the air intake duct.
• Use MAF sensor cleaner to spray and clean the sensor gently. Do not use any other type of cleaner.
• Reinstall the MAF sensor ensuring it is secured properly.

4. Check and Replace Spark Plugs (if necessary)

• Remove the ignition coil(s) to access the spark plugs.
• Use a socket set to remove the old spark plugs.
• Inspect the old spark plugs for wear; replace them with OEM or equivalent new spark plugs, ensuring proper gap settings as per manufacturer's specifications.
• Reinstall ignition coils and secure them.

5. Inspect Fuel System

• Connect a fuel pressure gauge to the fuel rail.
• Start the engine and monitor fuel pressure; it should match manufacturer specifications.
• If pressure is low, check the fuel pump, fuel filter, and fuel lines for any obstructions or failures.
• Replace any faulty components as needed.
