i just got a b16 swap done to my crx and after about 3 week of owning the car starts stuttering at about 3 to 4 thousand rpm. When it starts happening I even throw the petal to the floor and then a few seconds after it stops and then revs up and is fine over the 4000 rpm mark. I have had a similar problem where the fuel filter was clogged up because of it being so old in another car, could it be the same problem, need help please!!!!
