do you have similiar problems with the '79 slc? The reason I ask is that I am experiencing similiar conditions when the car has been driven heavily and then gets shut down for 5 minutes or so, and then I restart. It idles very low and dies if I don't give it some acceleration.

The '79 and '72 have very different fuel injection systems. My idle when cold is around 1200 and settles down to 750 when warm. This weekend I turned the idle adjustment screw 1/2 turn counter-clockwise. That seems to have helped.
