not too hijack this thread, but i too have a similar problem.
i have a 94 ex sedan and getting more and more hesitation while on the throttle. this seems to be getting worse if i run wot no problems, but if i run light throttle i get hesitation. i have replaced all this, new plugs, new wires, new cap, new rotor, new fuel filter, ran cleaner w/full tank of gas. 99% stock w/ exception of cai this has been on the car for a long time with no problems. now even more there is no cel. only once when i took a hard turn.
