Ron, MAF or AMM will cause it to stall as well. A real mark of a bad AMM is that it runs really rich and has an idle which wavers. It can be checked with a multimeter (digital) on the O2 sensor. If it is solid at a value higher than 0.6V or so, it is a clue of a bad AMM. Also if it is spitting water and black smoke out the tailpipe it is another clue. You just got the car. I would first rule out other issies first. Look for and fix any vacuum leaks (replace all vacuum hose on a car this old). Check and set the timing. get a set of plugs and possibly wires/cap/rotor if they 'need it'. Make sure the filters are OK.
