    Post the donor Civic year of the Y8 IM.

    Describe in detail exactly what "jerk off" means.

    If the IM is from a 99-00 Civic, it has the fuel air injection system that would cause idle problems when installed on a D16Y7 engine.

    You DO have a leak somewhere if your idle is fluctuating like it is.

    Doesn't matter what car you had it in. It matters what engine you put it on.

    Post pics of the IM.

    If your idle is going up and down repeatedly, you DO have a vacuum leak somewhere.

    A bad fuel pump would not throw a code. Are any codes currently thrown?
