When you open the fuel cap of your 2014 ASX and hear a sound of air being sucked in, it could be due to the pressure difference between the inside of the fuel tank and the outside air. This is usually normal and can happen because the fuel system is sealed to prevent fuel vapors from escaping. If the sound is frequent or you're experiencing other issues, it might be a good idea to have it checked by a professional.

10 Mazda 3 Star Version 2.0 frequently has the warning light on, with an instant fuel consumption of 30-40 at startup.

The check engine light is on for your 2010 Mazda3 hatchback, and the fault code indicates that the fuel trim system is too lean after the catalytic converter. Here's what you can do: 1. **Check for Vacuum Leaks**: Inspect hoses and connections for any leaks that might be causing the issue. 2. **Inspect the Oxygen Sensors**: A faulty oxygen sensor can lead to incorrect fuel mixture readings and should be checked. 3. **Examine the MAF Sensor**: The Mass Air Flow sensor might be dirty or malfunctioning, affecting the air-fuel ratio. 4. **Look at the Fuel System**: Check the fuel injectors and fuel pressure to ensure they are functioning properly. 5. **Check the Catalytic Converter**: Although less common, a failing catalytic converter can cause similar issues. 6. **Professional Diagnosis**: If you're unable to identify the problem, it may be best to consult a professional mechanic for a thorough diagnosis. Remember, addressing the issue promptly can prevent further engine damage.

Is there pressure in your ASX's fuel tank? When I open the fuel tank, there's air coming out.

After your ASX is turned off, can you hear a clicking sound from the air conditioning vents on the dashboard after about a minute?
