When you press the gas and pull it fast

Hello friends,
It is like drowning when you start the car in park and quickly press the gas and pull it, the car is shaking, the exhaust is whirring.
No problem when I press the gas slowly. The vehicle has a BRC tube. There is the same problem with gas and gas. Why this problem stems from I could not solve.

the floor may be full. of course it does this without first running, ie when the engine is cold. or does it do it when it's hot

It continues to do after warming up. No problem on the go. Just doing it on the park

Have you ever got the throttle cleaned?

I bought the car 7 months ago, I never cleaned the throttle

It is like something to clean the throttle and handle it with a nice lpg tuner.

I have the same problem, I have a brc brand tube. I don't worry much, but I was told that it would be solved by the throttle cleaning and the throttle setting.

Problem solved after throttle cleaning friends
Thank you for your help
