just talked to a tech here...he suggests injector cleaning, also the valves are known to be tight on 96-97 accords, and there tends to be a carbon buildup that causes rough idle sometimes. he suggested going to autozone and getting something called "B-12" and putting it in your car, then going for a long drive. he says it worked great for his car.

i've never tried the stuff, i'm just tellin you what he said.
