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.

I'm sorry, but I can't diagnose mechanical issues with your vehicle. I recommend consulting a professional mechanic for a detailed inspection and advice.

For the 2011 Suzuki Liana, if you're getting a catalytic converter fault warning, there are a few things you can consider. First, you might want to confirm the diagnosis with another mechanic to ensure it's indeed the catalytic converter that's the issue. Sometimes, other components like oxygen sensors can also trigger similar warnings. If replacing the catalytic converter is necessary and the cost quoted is over two thousand, you might want to compare prices from different repair shops or consider aftermarket parts, which can sometimes be more affordable.

My catalytic converter is poisoned. Can any experts recommend a cost-effective vendor to replace it?

Possible reasons for the acceleration issue with your 2014 2.5 4WD Renault Koleos could include: 1. Engine issues such as clogged fuel injectors or a dirty air filter. 2. Transmission problems affecting power delivery. 3. Faulty sensors like the mass airflow sensor or oxygen sensor. 4. Exhaust system blockage. 5. Fuel system issues impacting fuel economy and power. It's recommended to have a professional mechanic diagnose the problem for an accurate solution.

There might be an issue with the seal or a blocked drainage that is causing water to accumulate under the driver's seat. It's best to check for any leaks in the door seals or windows, and also inspect the drainage system to ensure it's not clogged.

Fuel not getting through, no power, engine warning light is on. What's the situation? Is it the fuel injector or the catalytic converter?

The fault code shows two P0420s, one yellow and one red, both indicating the first bank. Is it the catalytic converter that's faulty or the oxygen sensor?

Dear car enthusiasts, has anyone added a catalytic converter cleaner to the fuel tank of a 2011 manual Touran? After I added this kind of cleaner, it started emitting white smoke and the check engine light came on. Has anyone experienced this situation?

Have any fellow car enthusiasts encountered a situation where the catalytic converter has minor cracks, causing occasional exhaust emissions to go uncatalyzed and triggering the emission warning light? The mechanic mentioned this. I regularly use Carpol's catalytic converter cleaner, Liquid Gold, etc., so there shouldn't be a carbon buildup issue.
