Gas problem

I have a problem like this in my 306m I bought 1 month ago. While the car is in the first gear in the tube with very little gas, the speed of the car constantly rises and decreases. I have this problem in idling, the speed is rising and falling. I thought the problem was in the gas and took it to the aldesa service in ikitelli. First he started the car on gasoline and he said that it was very light at idle, and this event is happening when they are in the tube and they reflect it more. They said that I need to make the valve adjustment and the spark plugs should change. stop, there is really a problem in this situation. If this is not the case, I have to give high gas at the start, which affects fuel. I went to another service for spark plugs and valves, and they said that the valves of the vehicle were hydraulic, they said no adjustment was made. I am waiting for your help and ideas, friends. thanks
