Release the throttle at high speed of 5000 rpm, and the oil receiving exhaust pipe will sound like tempering. Is the exhaust pipe draining normally?

I don't know which car you have for several years. If there is power attenuation, there may be a problem with the oil cylinder pipeline or a lack of oil cylinder. There is also a blocked throttle and carbon deposition. Lead to uneven exhaust and panting. If it is intermittent, you can pull up the speed. If there is no speed measurement, try to run as fast as possible, so that the car can drive at high speed for a long time and automatically clean the throttle. You can also go directly to the repair shop or 4S to clean the throttle. In my Cruze shop, the idle speed of the new car was unstable, and the engine software was upgraded to alleviate it. To be sure, it has nothing to do with engine oil. I hope I can help you.
