Default still have a few problems on b18a/b swap

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?

i've had friction noises under the hood that I couldn't hear during acceleration, but it turns out that was just because I couldn't hear it over the engine noise. Did you check the timing belt cover at all?

yeah, i checked it. i took the top cover off, then turned the engine on (the inside cover and the bottom cover over the crankshaft was still on). everything seemed fine. i put the top cover back on, and felt it for vibration while idleing. i pushed against it, and when it hits the timing belt, there's no doubt about it, you feel it moving against the cover. when im not pushing, it doesnt feel like its hitting at all. only vibration from the engine. plus you can hear it when it hits, and it doesnt do that unless i have it pushed in (very briefly of course).

any other ideas on these 2 problems?

so... it idles high until your car warms up and then it goes nuts?

This sort of thing is common after doing major engine work. You crossed up the wires for your EACV and the Evaporative Purge Solenoid. They have the same connector and are very close together on your engine harness. One of the wires on the EACV connector is blue with a yellow stripe. The purge control has a red wire. Both have a yellow wire with a black stripe (power +).

Makes a great practical joke. Amuse your friends, and you'll surely be loved by all! :nono: ...either that, or for the rest of your life you'll be ducking and dodging sharks with laser beams.

As for the timing cover idea... I have no idea what you're talking about. When what hits? Push on a who? What engine noise? What's moving against the cover and why would you push on it? If you don't, it doesn't rub? Wha?:dunno:

If you're adjusting your idle by tightening your throttle cable, then someone has to smack you, or you need to smack whoever told you to do it that way. Loosen that thing up, so it's just tight, not opening the throttle AT ALL. Then reset your ecu, and start it back up. Adjust the idle with the valve on the TB.
The ticking, is it more of a metal on metal sound? Sounds like it could be rod knock... Could also be exhaust noise. I know with half the swaps I've done, it ends up pushing on the exhaust just a little, and it may be bumping the heat sheilds on the frame.
