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?

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?

I have a 2007 Touran, automatic 1.8t. It jerks noticeably during acceleration. When idling while parked, the RPM intermittently drops by 100-200, and the car lights dim. What should I do? (I've previously cleaned the fuel injectors and throttle body.)

When driving the 2017 1.5T Smart model at 55 mph, the engine makes a roaring noise, but it disappears after accelerating past 60 mph. I've cleaned the throttle body, removed carbon buildup, and changed the engine mounts, but the issue persists. I've heard that reprogramming might help, but it carries some risks. Has anyone encountered this problem?

The engine fault code flashes at idle and stays on when starting. The fault indicates a misfire in cylinder two. After replacing the ignition coil and spark plugs, and cleaning the injectors, the fault code disappeared but returned after two days. Do you know what might be causing this?

Hello fellow car enthusiasts, have any of you cleaned the throttle body before? I've heard that cleaning the throttle body on an MG3 is quite a hassle, taking up to 5 hours and costing 500 bucks.

The car is a 2015 model and has run 99,000 kilometers. The warning light turned on, and you replaced 4 ignition coils and 4 spark plugs. After some time, the light came on again, and the engine shakes when starting, but it's still drivable, though the light remains on. What's causing this issue?

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.

The engine malfunction light on my 2010 City recently started flashing. Diagnostic code 14 indicates irregular misfires. I've replaced the spark plugs, ignition coils, and cleaned the fuel injectors, but the issue still occurs intermittently. Every time the light flashes, I restart the engine and the issue disappears for a while before reappearing. Any knowledgeable experts or fellow car enthusiasts have any advice on how to handle this issue?

The dashboard shows a warning light, and when checked with a computer, it indicates an ignition module issue. Should I replace the ignition coil? There are no problems when driving normally.
