yes the air hoses are old and most have cracked , and messes up MAF readings big time.
well the IAC needs to work cold. but your having hot start problems. IAC is closed hot.
seafoam is no cure, but the gunk under the throttle valve , will not stop starts, its closed 100% ,until you step on the throttle.
what works is clean parts by hand, no magic to that. and is hard work,.
the iSC must be free to work, or hot starts will be very difficult, lacking fresh metered air.
sure id use sealant, there are many kinds, most work. ok
6mm bolts are all about 89 inch/lbs torque, (inch not feet) divide by 12 to get feet.
get ISC freed up set duty cycle hot, and it now idles all day at 800rpm
the TPS idle switch must be closed, and 0v or the ISC is born dead.
the isc is open at 12v and closed at 0v.
the video you can hear the snappy clunks. (it can leak a tiny bit closed, no problems, most do this old)

IAC a big pain, so if its closed hot, and open cold, its ok, just leave it be...
