86-89 INTEGRA DOES NOT HAVE A FITV.

I really need help on this and no one on other forums have responded to anything I post, this seems like an active forum so maybe I can get some help.

IVE REPLACED...
IACV with a brand new one
I replaced the Cylinder position sensor with a brand new one
I replaced the o2 sensor with a brand new one
Ive cleaned the throttle body fully and tightened down intake manifold
Cleaned PCV

Im throwing no check engine light

When im driving and I push in the clutch in the car idles low for a second and jumps back up and stays normal.

If its warmed up if I turn the heater and defrost on it doesnt idle up and down in neutral but still when I push in the clutch it idles down and goes back up and stays normal.

Im confused and need some help, could it be my thermostat being stuck open? Vacuum leak, ive checked all the lines and there great, any ideas?

it may be normal.. how low of a rpm does it sit at for a sec? below 400? and how long till the idle fixes itself usualy?
