Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, fuel pressure gauge, cleaning solvent, basic hand tools.
• Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Address Error Codes

• If error codes indicate specific issues (e.g., P0171 for lean condition), follow manufacturer repair guidelines for those codes.

3. Clean or Replace Throttle Body

• Tools Required: Socket set, throttle body cleaner.
• Remove the intake duct to access the throttle body.
• Use throttle body cleaner to clean the throttle body, removing any carbon deposits.
• Reinstall the intake duct and reconnect the battery.

4. Fuel Pressure Check

• Tools Required: Fuel pressure gauge.
• Locate the fuel rail and connect the fuel pressure gauge.
• Turn the ignition to the "ON" position without starting the engine and check the pressure reading against manufacturer specifications.
• If pressure is low, consider replacing the fuel pump or fuel filter.

5. Inspect and Replace Spark Plugs

• Tools Required: Socket set, torque wrench.
• Remove the ignition coils and spark plugs.
• Inspect the spark plugs for wear and replace if necessary.
