I've got a 2013 Kia Sportage Manual GL 2.0, and the steering wheel shakes when idling. I've cleaned the carbon buildup in the engine cylinders, the injectors, and the idle valve. I also replaced the spark plugs and engine mounts last year. Any experts out there have any advice?

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]

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?

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?

Have any of you cleaned the throttle valve? Did you do it at the dealership or another repair shop?

It could be due to several reasons such as engine misfire, idle air control valve issues, or even problems with the transmission mounts. It's best to have a mechanic check it out to diagnose the exact cause.

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.

My Jietu X70 has run 30,000 km, and when I cold start it, the idle is unstable, and the car shakes. After about ten seconds, it gets back to normal. There's no error displayed. I left it at the 4S shop for a week, and they cleaned the throttle, carbon buildup, and fuel injectors, but it didn't help. The 4S guys said it might be the fuel, so I switched gas stations, but there's still no change. Has anyone else experienced this? How did you solve it? Please let me know. 🙏
