10 Mazda 3 Star Version 2.0 frequently has the warning light on, with an instant fuel consumption of 30-40 at startup. Spark plugs, intake manifold solenoid valve, rear oxygen sensor have been replaced, throttle body and mass air flow sensor have been cleaned, but the light comes on again. The first row mixture is too lean. Any suggestions?

Is the fuel consumption for the 2009 Liana 1.6 automatic reaching 10 liters per 100 kilometers because of a faulty oxygen sensor or carbon canister purge valve? I've checked the spark plugs and ignition coil, and there are no issues. Any advice from the experts?

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.

When coming to a stop, the idle speed suddenly drops and it feels like the car is about to stall. This occasionally happens when shifting from D to P while stationary. I've replaced the spark plugs, ignition coils, injectors, high-pressure fuel pump, PCV valve, carbon canister solenoid, air flow sensor, and engine mounts. I've also cleaned the intake carbon deposits and combustion chamber carbon deposits. The problem still exists. Can anyone help me figure this out? [crying][crying][crying][crying]

After a major maintenance on the 2006 Accent 1.4 manual, the spark plugs, carbon canister solenoid, and throttle have been replaced, and the fuel injectors have been cleaned. With the fuel price at 7.91, it's costing 0.9 per kilometer. Is this normal? The oxygen sensor is fine!

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.

The 1.4T model keeps showing a fault light, and there's no 2nd, 4th, and 6th gear. The computer, valve body, and clutch have all been replaced, but the issue persists. How can this be resolved? Has anyone encountered this?

Why does the engine light keep coming on in my 2017 Kia Pegas automatic? After resetting, it lights up again after driving for a while. I've already replaced the oxygen sensor, but the problem remains.

I have a 2019 automatic RIO, changed the front and rear oxygen sensors, but after a few days the fault light comes back on! How did you guys solve this issue? What's your fuel consumption per 100 km? Mine is currently 10 liters per 100 km.

The 2014 model with a 3.5L engine shows the engine warning light and exhaust system fault light at 100,000 km. The sensors have been replaced, but after a while, the lights come on again. Does anyone know what the reason might be? Generally, the lights only come on when driving at high speeds. Could it be related to the Evans waterless coolant that was changed a few years ago at the 4S shop?

If your 2010 Suzuki Swift 1.5 automatic is still shaking after replacing the spark plugs, ignition coils, PCV valve, and EGR valve, there could be other issues at play. Some potential causes could be: - Engine mounts: Worn or damaged engine mounts can cause vibrations. - Fuel injectors: Clogged or malfunctioning fuel injectors can lead to engine misfires. - Throttle body: A dirty or faulty throttle body can affect engine performance. - Air intake system: Check for any leaks or blockages in the air intake system. - Transmission issues: Problems with the transmission can also cause vibrations. You may want to consult a professional mechanic to diagnose the issue more accurately.
