ics malfunction? I dont understand. I have a 97 civic dx with a d16y7. The motor was from an automatic and i have a manual.

My idle is at 2000rpms and then sounds like i have cams because it goes from 2000 to 1900- 2000-1900-2000-1900 real quick.

help me anybody

 

idle air control valve is faulty. replace it. its on the back of the intake manifold. i know you can clean them out with brake cleaner but i was told it doesnt work to great on hondas/acuras. (Also it being just dirty wouldnt throw a code.) most likey an open in the solenoid.

 

nah i have a y7 so its on the throttle body

 

its on the tb cause it was an auto engine manual and it would be on the back of intake mani

 

and i just cleaned mine with carb and choke cleaner and it worked like a charm

 

No. Its a Y7, they're all on the throttle body.

-D16Y7 -> IACV on throttle body, both automatic and manual
-D16Y8 -> IACV on throttle body on automatic versions, IACV on intake manifold on manual versions.

 

well yes check the iacv but you dont need to go buy a new one.. i dunno what you heard but from what i've seen and heard it works just fine if you clean it with brake cleaner

 

i cleaned it with brake cleaner. its still ****ed up

 

as stated before, if its not throwing a code and is idling funny, cleaning will work.

if it is throwing a code then usually it needs the whole IACV cause the solenoid is fubar.

also, if you clean one too many times the valve will end up dieing on you.
