1800 cold idle is perfectly normal, dlstech.

My engine use to do the same thing, if you say the the TP cable has enough slack hen you should try out cleaning your FITV, its under the TP

Really? I mean I know engines have higher cold rpms but more than twice the normal? And I don't think I have a FITV, this is a 2000

My 98, pre-turbo tune, idled at 1650 on a cold start. My mom's H4 subi idles at 1600. My step dad's Subi H6 idles 1500. 1800 is safely within that range.

having an air pocket inside the IACV and the hoses that go to it

would this also cause the throttle body to get really hot. too hot to touch? the air box and air filter really hot as well? i burnt my finger by using the throttle directly from the throttle body (the thing the throttle cable wraps around)

of course the engine was at operating temp (95 C)

Everything in the engine bay gets hot.

that doesn't answer my question. ever since i took off and cleaned my IACV the throttle body and airbox are getting much hotter than normal

from the sounds of it your better off replacing the IACV.

There is a small seal inside the unit shaped like an o-ring that rests on the end of the plunger, or in the boss that the plunger sits in when closed (cant remember which)
This seal can fail from wear, age, in your case it would most likely be from cleaning it at its age and buildup.

I have a 2000 civic si with 143,000 miles and it wouldn't hold idle at first cause the unit was stuck shut from most likely from the car sitting for 3+ years with a blown motor. I douched it like everybody else and slightly tapped on it with a hammer while applying 12 volts to it and it became unstuck, and also torn/damaged the seal. Now my idle was 1,000-1,500RPM, along with hunting/fluctuating high idle. This was quickly followed by
P0505. after removal of the part I could clearly see a section of the round rubber ring hanging out of place and obviously shot. I suggest you inspect yours also.

I have since replaced it with a new OEM Honda unit.
No problems since.

And from my experience with Hondas along with many other makes and models. cleaning air bleeder valves is only a temp fix for the most part. And many vehicles I have seen start to exibit problems again within a few months. Hondas go longer though if cleaned, but you have done that.

And what sux most, they don't come cheap.
