Solo is most likely changing a fuel mixture and then restabilizing.
Flooding the intake, would analogous to a jet engine cause a change in the 'air-fuel'1 mixture of the sublight drive.
Suddenly changing the 'air-fuel' ratio of the Millenium Falcon, would, like in modern jet engines cause some instabilities and potentially stall the engine. One can assume ...

Since gravity is inversely proportional to the square of distance, a ...
