Is it normal that the idle jitter increases obviously after the dual clutch replacement?

Hello, two possibilities! One is that the newly installed clutch cannot be completely separated due to mismatched installation and debugging, and the other is that the air intake system is too dirty, and the weather is getting cold and the jitter is obvious, which has nothing to do with changing the clutch. Check the air filter and throttle valve. If the mileage exceeds 70,000, please check the spark plug. If the answer is helpful, please adopt it.
