Idle air control valve
My idle is ------ crazy sometimes its steady then the rest of the time it jumps anywhere between 1200-and 2500 RPM its just jumps and its annoying. Is that my IAC valve? or should i just adjust my idle? Thanks

Re:Idle air control valve
mine will bounce like that but between 700 and 1500 rpms and only when the motor is warmed up completely
UPDATE: tried vacuum hoses and no good, had a loose battery connection and now that it's fixed, no more problems

I don't think its a vaccum leak becuase you would hear it. My Integra was doing it until I put a turbo on it than it stopped. My friends 01' Prelude just started doing it too and its very annoying.
Please update on how you fixed it cause' I'd really like to know

Re:Idle air control valve
this good and all for HIGH idles.. what about low idles? mine idles 100% PERFECT when cold 2k. but when warm it stumbles around 500rpm.
half warm its at like 1k - 1.2k smoothly. Anyone have some guesses?

Re:Idle air control valve
stumbels like minor surge or like a missfire?
MINI vac leaks can play hell So can a SMALL bubble in the coolant lines.
I have one on the 89 HB i sold my roomate i am still going thru that thing trying to find it i think its under the DPFI plate there is a o ring in there and a gasket i bet is shot on this one....

Re:Idle air control valve
yah the idle doesnt go up. it stumbles and falls to like 300rpm then kinda catch itself and go to 600 and then settle back to 500 again. but when cold or warming up its fine. i think my iacv is dirty or done. I've got an entire IM coming w/ tps etc.
