[3.2 CAB]

As far a giving the engine a little rev. blip before turning off, I have seen this done a lot over the years. I remember that my father, would do it, he gave no explanation as to why, and I didn't ask, but I do remember him doing it, along with almost everyone else that was driving in the 1950's. I know that my mothers dad, my grandfather, owned and drove a dump truck far as long as I ever knew him, he would do it also. I was very young and I never asked why he did it. I did see almost everyone, people that I didn't know also did this, that was driving in the 40's, 50's 60's and even into the 70's did this. I know that I don't blip the accelerator right before I am turning the ignition off, but I will sit there, a few seconds to let the engine idle level off after a drive, or after pulling the car into the garage, or when I get to where I am going. I do let it idle just a few seconds, just to let it get back to a smooth idle, about 10 seconds. I also make sure the car is in neutral before starting, I guess that this is not really needed to be done, being most cars now with a standard transmission, have a clutch/neutral safety switch, that won't allow the engine to start, unless the clutch is depressed, or on an automatic transmission, that it is either in park or neutral.
