Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Allow the engine to cool down before starting work.

2. Inspect and Clean the Throttle Body

• Tools Required: Throttle body cleaner, socket set, cleaning cloths.
• Remove the intake hose connected to the throttle body.
• Spray throttle body cleaner into the throttle body while opening the throttle plate manually.
• Wipe clean with a cloth to remove carbon deposits.
• Reinstall the intake hose and ensure it is securely fastened.

3. Replace Air Filter

• Tools Required: None specific, but a socket set may be needed.
• Locate the air filter housing.
• Release the clips or screws holding the air filter cover.
• Remove the old air filter and inspect for dirt or damage.
• Install a new air filter, ensuring a snug fit and replace the cover.

4. Test and Replace Spark Plugs (if necessary)

• Tools Required: Socket set, torque wrench.
• Remove the engine cover if applicable.
• Disconnect the ignition coils and remove them using a socket.
• Remove the old spark plugs using a spark plug socket.
• Inspect the spark plugs for wear or carbon buildup.
• Install new spark plugs, torquing them to the manufacturer’s specifications.

5. Check Fuel Pressure

• Tools Required: Fuel pressure gauge.
• Locate the fuel pressure test port on the fuel rail.
• Connect the fuel pressure gauge and turn the ignition to the "ON" position (without starting the engine) to check for proper pressure.
• If pressure is low, inspect the fuel pump and filter for issues.
