i have a 91 integra gs and i ran into a problem.When i drive it it shutters at 3k rpms and below anything above that it drives fine.Im not sure what to do i gave changed the distributor,the cap and the rotor and did a basic tune up and its still doing it>now it only does it when you put it to the floor if you put the gas down slowly and only about half way it does ok im no5 sure what it could be could use some feed back thank you.Oh by the way the motor is a jdm b18 from japan.
