The "floating" turns gradually result in a machine starting to swallow. In this case, it is recommended that the spark plugs be changed first. If you don't have any changes after that, you can try to fill the gasoline at different gas stations. If it doesn't help, it'll probably have to go through the reupholstery.
In addition, the fuel pressure at the intake manifold, a malfunction in the air flow-meter, may be the cause of the malfunction. The cause may also be the contaminated throttle.
