Check there is no broken air lines or small cracks in the pipes spray carb cleaner around the air lines and see if the engine idling sound changes, any splits in the rubber connections replace. also clean out the air intake, can use the carb cleaner and get any dirt of the butterfly valves, check the colour of the dis cap white res on the pins clean them with some emery cloth so they are clean, check plug leads make sure there is no hard no flexy parts if stif replace. check the spark plug gap on the spark plugs, also check there colour these is a colour chart for spark plugs check and see what color yours are to the chart, this can tell you if your mix is correct or not. do this for now no part should be needed unless spark plug leads need replacing.

Just off the top of my head, guesses: Given what you've already done and the high mileage, could be carb, but I'd start with fuel filter and a good additive like Sea Foam. Also, you might want to replace the PCV and any other sensors which may be suspect.

That is usaully the vacuum advance diaphram on the distributor. Its job to advance the distributor when at idle. The diaphrams inside rot and leak air, causing it not to advance. Take off the distributor cap and use a vacuum pump to individualy test each port (two of them) on the vacuum advance diaphram. You should see it pull back, if not replace it. They are sold at your local auto store, oddly its cheaper to get a whole distributor that has one for $100 that to get it alone for $150.
