    i just got a 91 si that had a d16y7,,i took the y8 head off of my 98 and put it on the y7 block with the 91 si intake, that has 98 ex injectors with obd2 clips,,,the car starts and idles put when you rev it up,,it starts to bump bump bump, at 1500, and the higher you rev it the faster the bump bump bumps are,,,it sounds like it has 2 stage or something.

    the only code im getting is 14 atmospheric pressure something,,,

    obd0 dizzy
    pm6 ecu
    91 si engine harness
    msd rpm activated switch (vtec)
    adjustable cam gear 4deg adv.
    y7 timing belt

    does anyone have any idea what the problem is? i have tried jjust about everything,,,i would really love to get this problem solved,,, ive checked a few other forums and no one has helped,,,
