Hesitation after burnout.

At it's very basics. A hesitation is equal to hunting for more fuel. The motor is waiting for something to ignite. When it finally collects enough and catches up, "Bam", off she goes again.

A sputter is the opposite. The ***** is drowning and has to spit some out before she catches up again.

And when you say you give it. Is this a slow or a fast given. Are we mashing or getting on an on ramp at the freeway? or is it autobahn
