Gene, from personal experience, it could be the flow meter rheostat needing cleaning. If you haven't looked at the inside of one, there is a wiper arm traveling across a potentiometer variable resistor on a printed circuit board.
If the circuit board becomes dirty, prying the cover off the flow meter, and cleaning the copper pot surface with contact cleaner or brake cleaner should
solve the problem. The cover can then be resealed with clear silicon sealant.
Do not be tempted to adjust the arm tension or play with the spring tension
of the air flow paddle to make the engine run leaner or richer. You won't really
help anything doing that and could cause the pot surface to wear faster.
