Well for one thing, I'd check easy stuff first. Look for vacuum leaks. If an autotrans check the hoses running up and down to the manifold; and the modulator down by the side of the trans. Check pvc hose and the grommet where it goes into the valve cover. Replacing the grommet helped me once. It should be a snug fit. Make sure the carb is secure on the manifold. Replace the fuel filter at the carb cause it's easy and cheap. If you have power brakes I'd check that hose too and the check valve on the booster.
I'd make sure engine is tuned up, good spark plugs, wires and all. Good chance you may need to rebuild the carb. It's not hard. For the time being you could adjust the idle speed and mixture screws to see if that helps.
And you need a service manual. Preferably the factory one.
