I've got a 2012 Changhe Liana, and it's been having issues with shaking at idle, while driving, and even more when the AC is on. I've already replaced the spark plugs and ignition coils, and cleaned the fuel injectors and throttle body, but the problem persists. The check engine light comes on frequently. Does anyone know what might be causing this issue?

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.

I bought a used Liana and it's burning oil. What should I do?

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?
