Have a 1988 Accord with an a20a. Carbuerator was bad changed that changed filters changed trottle spring. Still have a problem though. Driving on the highway it just loses speed and starts choking out. Wondering if you know what is wrong with it.

 

Which filter is new? Fuel filter??

Pull spark plugs & look at them for evidence of rich, lean, whatever... How's your spark timing? Does that car have mechanical stuff for vacuum & centrifugal spark advance? Something loose in there?

Other ignition troubles usually cause jerking or uneven running. Smooth loss of power sounds like fuel or maybe your spark timing is wandering around.
