well...sounds like your AAR is working and you'll need to work on your tune up.

AAR = Auxiliary Air Regulator

the aar is a sort of like a valve that's open when you start the car. It produces a artificial air leak. As it warms up, the valve closes. Then you car should idle around 950rpms.

the usual, have the valves been ajusted lately. then dwell and timing...then you could adjust the screw on the throttle body to get the idle around 950

yes...just start with the basics.

you really should drain the gas, and maybe clean the tank. You don't want to crap up your fuel injector with bad fuel.
drain and change the oil....
Then you'll want to adjust the valves. There are some how to do threads on this site that could help.
I like to replace all the stuff on top. Spark plug wires, spark plugs, rotor, points, etc....
then put some new gas in there and fire her up!

yes...certainly check the dwell then time.

could this be a simple Idle screw adjustment on the throttle body??? counter clockwise to increase idle!

once the car is warm or the AAR is closed...the car sits for a short time (the AAR should still be closed) does it still start up, idle high then crap out???
...if so, maybe you should check out some part numbers. MPS, ECU, make sure the PO didn't make your life a challange!!

nothing...sounds like your learning.... (IMG:style_emoticons/default/beerchug.gif)
check the oil level after sitting for a bit to be sure about the level.
