Hey car enthusiasts, my 2018 MG6 manual shakes a lot and lacks power during sudden acceleration. The computer diagnosis shows an intermittent misfire in the fourth cylinder. What could be the reason?

I own a 2014 SsangYong Korando, 2WD high trim, 2.0 gasoline. Recently, the check engine light occasionally turns on with the error code indicating a misfire in cylinder 1. Sometimes it turns off by itself. I've swapped spark plugs between cylinder 1 and 2, ignition coils between cylinder 1 and 3, and even swapped the injectors. I planned to use elimination to check if it's the injector issue, but after each swap, the misfire code for cylinder 1 still comes back eventually! The engine idles with slight vibrations, but I don't feel any power loss on the highway—it easily goes over 160 km/h. Later, I measured the cylinder pressure: cylinder 1 is at 8 kg, while the others are over 10 kg. After researching online, I suspect it's an exhaust valve issue. Now I'm really torn. Should I just let it be, or go for a major repair? I read online that some people can fix it by opening the cylinder head without removing the engine. But the local big auto shop is no more, and the private mechanic suggests removing the engine, which I really don't want to do—worried it won't fit back as perfectly as the original. It's stressful because I bought this as a first car for my father, who has loved cars all his life, and now this happens. I've been to various places without a clear diagnosis. Some say it's slight cylinder wear, some say valve leakage, and others mention cylinder head design flaws. Any advice from fellow Korando owners on how to solve similar issues would be greatly appreciated!

What could cause the steering wheel to shake during sudden acceleration? Today, when I suddenly accelerated, the steering wheel shook a lot, and I'm not sure what's going on.

I have a 2018 V40, and when I start it, the steering wheel and the center console panel shake a lot, especially when I turn on the air conditioning. It's only run about 50,000 kilometers. It takes quite a while for the shaking to reduce. What could be the problem? Has anyone else experienced this?

I have a 2012 Subaru Outback with an EJ25 engine, almost 200,000 kilometers. It has noticeable shaking at idle and stalls during sudden braking, especially when the engine is cold. I cleaned the throttle body carbon build-up recently, which improved it a bit but didn’t completely solve the problem. The engine is quite loud during hard acceleration, and I’m not sure if it’s the engine or the transmission. Also, recently it shakes at speeds over 100 km/h. Anyone experiencing the same issues?

In the 2019 JETOUR X90 Enjoy Edition 6-seater with a 6DCT dry dual-clutch transmission, currently at 120,000 kilometers, an issue has been occurring since around 90,000 kilometers. When starting the car cold, everything is normal during acceleration. However, after driving for about half an hour and the engine warms up, when stopping or waiting at a traffic light and then trying to accelerate again, the car doesn't respond to the throttle. If you press the throttle harder, the engine stalls. When you feel the engine shake while pressing the throttle, if you release the pedal immediately and then press it again, the car can start moving, and everything works normally after that. There are no fault codes detected by the computer, and the spark plugs have been replaced. The engine checks out normal at the 4S shop. I'm seeking advice from experts on how to resolve this issue or if any fellow JETOUR X90 owners have experienced a similar problem and how they got it fixed. Thank you very much for your help!

I would like to ask if the stability of the Peugeot 308 1.2T has improved a lot after the 2018 model? Or is it still the same as before, with issues like oil burning and cylinder scoring? Can any real car owners share their experiences?

My 2015 manual classic model is shaking a lot when I drive it, and the sound is like it's gasping for air. The power also seems to be lacking. What's going on?

Hey car enthusiasts, has anyone experienced shaking during sudden acceleration? It shakes after driving steadily for a while, especially noticeable at high speeds. The 4S shop only cleared the previous driving habits, which improved slightly but didn't solve the root problem.
