well it wasn't the isc.
then i listened some more today, and my roommate agreed.. turboside... hmm. so im gonna have to narrow it down from that side of the uim/lim to the turbo
still noticing that if i rev up slow and down slow , no squeek. any quick release or rev and it will. oh and its idling at 1.5k is that just normal for rebuild or is high idle possibly related to this issue?
