I have a 1998 civic ex 5spd and it has started to buck and stutter at low rpm and lose power at midrange around 3-45k, I just replaced the plugs, distributor cap and rotor and it's currently running 3 code, knock sensor 1, downstream 02, and idle air control valve, would it be one of these or a combination of all of them, it kinda reminds me of when my pip sensor went out it my 86 f150, accept it will idle but sounds like it's misfiring when it starts hesitating on the highway and idling
