When I was a kid, whenever someone was shutting down their car, they would kill the ignition, then just before the engine was stopped they would tap the ignition back on and off a couple times. What was that all about and why did it dissapear?

What you probably remember is someone trying to stop the engine from "running on" due to what was called "dieseling".

A lot of cars built in the 60 & 70's had a problem with this due to carbon build up, smog equipment and octane being lowered. Sometimes a bad tune up was a contributor. After the engine was shut off it would huff, puff and continue to try and run. It was worse when the engines were hot and sometimes would go on for 20-30 seconds or more.

My buddy used to turn his car off. Then immediately restart it. Then turn it off again. It drove me crazy. He said, "I want to make sure it is going to start again."

Back in the day it was done to try and clean out gas that would puddle on the floor of tunnel ram manifolds. And made it easier to re-fire the motor the next time.

That might be one reason fuel puddling and another might be checking kill switches. if i remember it right there was a autometer tach that would refire the engine a few seconds if you checked the rpm limiter? MSD ignition without the diode in the + wire to the alternator would also cause it to stay running. just my 2 cents worth
