In 2008, Ma 6 2.0' s car was boring, but the cold car was ok. The hot car is stuffy, and the valve is still a little noisy. It is always difficult to climb a big slope in terms of revolutions and speed. Hello!

According to your description, it should have little to do with the engine cylinder pressure, which is not easy to happen in a six-year-old car.

I suggest you go to the 4s shop to check several places.

First, check the gasoline pressure and oil output. It may be that the oil pressure is insufficient or the pipeline is blocked.

Then check the ignition system and try to replace the spark plug.

Finally, use the decoder to read the health status of the car.

I hope I can help you. If you don't understand anything, you can adopt it and ask!
