Is it revving up when the car is idling? Is the idle speed higher than it should be? If so, you either have a vaccum leak, or your idle air control valve is bad. Sounds like the second, but i'd take it by autozone and have them pull the check engine light codes to be sure. They do it for free. If they say its a vaccum leak, let me know and I'll explain how to find it.
If you don't have a check engine light, Start with the air and fuel filter, work your way up to a tune up. Clean the throttle body as best you can on the inside, behind the throttle plate/s
In general, yes. This is a carb tuning issue. Another possibility is a vacuum leak somewhere, but most likely, it's a carb issue. You'll typically see your rpm drop a bit when you put it in gear, but that it sometimes stalls out points to a carb issue.
there is a wiring problem with some of them the wire shorts under the intake manifold that runs to the alternater. also the alternator on them seam to have a mind of their own and only work when they HAVE to and test good when load tested replace alt if the wires arent shorted
