  Hi to all....
  
  Is it an urban legend that you should rev ur car before you switch off the engine... heard that it clears the carbon?? But most cars now use fuel injection... so does this still apply? I heard the Shell Radio ad saying that it is not good for the car.
  
  Anyway, IMHPO.... I feel that iz juz the driver tryin to gain attention from ppl around him/her to look at them in their cars! POSERS!
  
  Cheers

  The old cars back then that use carburetors sort of like needed it to be revved up due to fuel vapour left in the combustion chamber.
  
  The newer engines that uses fuel injection eliminated the problem above. So there.

  Read somewhere it's not only unnecessary, it's also bad for your engine.. think it's on the shell website where they tell you how to maintain your car, etc etc...
