A bad distributor could be the source of the problem. I agree with the
other posters--for example--dirt in the carb. could also cause the
problem.

You might consider taking it to a mechanic that has one of those huge
computerized machines. He or she may be able to find the source of the
problem. In the long run--it may be cheaper than replacing various items
that are working great.

 

There aren't very many computers that will help you with a carb accord....
just the factory service manual and a lot of time
