Im thinking this has to be a vac leak, but Ive replaced every gasket on the intake. I have IAC control but while this is happening, the IAC isnt moving at all, sitting at where it would normally idle but not engaging because RPMs are changing too fast. Map is going from 40-80 kPa. Normally sits at 55 at idle.
