I searched to no avail...

My hatch recently started reving at idle on it's own. It's just a constant rev up to 2 grand then back to idle over and over again. It doesn't do it when i first start the car up, it seems like it has to get warmed up. Anyone experience this?

Thanks guys.

sounds like it could be a vaccum leak. happened with a friends of mines car after he swapped a gsr in.

yep what jdm123 said i think its a vaccum leak

could be your IACV (idle air control valve), its a common problem w/ hondas. screen may be clogged. try cleaning the carbon deposits on the IACV screen. just remove it from the back of the manifiold (2 bolts), disconnect vacuum lines, clean it, put back on and see if it makes a difference

Could be this. However, when it happened on mine, I adjusted my idle adjustment screw on the intake manifold and it fixed it.

if its not those .. just listen to the guy abotu the Idle Air Control Valve... my friends was having that problem and he replaced that.... also a vacuum leak is possible too... just go through and check

i recently installed a TBS on my intake and it started to rev at idle, i cleaned out the iacv but it still continues to rev.

jdmpremonition

a friend of mine had that same problem and he found out it was his o2 sensor. you might want to try that if nothing else works...

I have the same problem, but it goes away after I'm warmed up.... and it only happens when I hit some gas before its warmed up.. 1.2k-2k rpm..... 1.2k-2k rpm..... up and down

it could be all those problems but deepding if your engine is moded with turbo or some sick na setup your car might be running to rich to the ECU at idle revs your car to compensate for the extra fule at idle when it is warmed up

exactly...

im gonna try getting a new iacv and trying that out.

well i took the TB off my car today determind to fix the reving problem, turns out that apiece of my old TB gasket found it was into the orphis to the iacv so i shot it dosn with some TB cleaner and swabbed it with a cotton swab now it all better. and i found that my TB was insanly dirty and i ahd just cleaned it out not even 100 miled ago. So i inspected and found that my airfilter had a rip in the inner linning leaving a hole for all sorts of things to enter my intake, since im broke i just mendid it with some fabric softener sheets till i get paid.
