So ive been having a idle surge problem and i replaced the intake manifold gasket and it got somewhat better. it used to bounce from 1-5k but now its only 1 to barley under 3k. i didnt have a torque wrench so i didnt tighten those manifold bolts a lot out of fear of over torqueing. so idk if its just that they arnt sealed properly because somtimes if im sitting in a parking lot with it surging and i just rev it up to the limiter it stops surging and idles normally. any help would be appreciated i replaced the iacv with one from a f22 because i read somewhere that it will work the same.
