man, i can't figure out wtf is goin on with a few more things. i thought i had them, but i don't.

first of all, the idle is really strange. i adjusted the nuts on the throttle cable bracket yesterday, and it was idling beautifully at just under a grand ('bout 800 or so the best i could tell) which is right where it should be (when warmed up). then this morning, the idle was all freakin crazy when it warmed up (started at 1500k when cold). it would stay at about 7-8 but only with the clutch pushed in. when i let off the clutch, it would drop like it was going to die to about 100, then reach back up to maybe a couple hundred, then would fluctuate between the two. do i have a problem with my IACV or what? if so, how the hell do i fix it?

secondly, i have a ticking noise, but only when im decelerating. ill be driving just fine, then when i start to break or even when i just put it into neutral, there's a ticking noise (never on acceleration though). i've had this problem, thought it was the valves, and checked those the other day. all are within specs. it still wont go away. i took my car in for an alligment, asked the guy what he thought it was. he told me it was the timing belt cover rubbing against the timing belt. i could be wrong, but that sounds pretty god damn stupid to me since the ticking is ONLY on deceleration. any ideas?
