   Your Sienna is injecting into the intake of each cylinder, so the computer   
   has fairly independent control over cylinders.   But there is still a   
   very tiny amount of mixing in the manifold.   
      
   Cars that have direct injection (which include a lot of newer BMWs) inject   
   directly into the cylinder rather than the intake.  This requires much more   
   rugged injectors and much more expensive ones.
