hi my 96 civic just all of a sudden have a weird idle problem when its in park. sound like the engine is reving up and down. but when im in D4 it doesn't make that sound.

Clean IACV and throttle body then report back with results.

yes correct the iacv i just cleaned mine with carb cleaner. was doing the same at idle. now seems to be fine. that part is not cheap cleaning is your best bet

I tried looking for the IACV but I cant find it, I googled where it located but the pic is different from my engine. I have a intake box on top of my engine and all the pic doesn't have a intake box. any 1 can help me figure out where it located? people say its behind the intake manifold but couldn't find it

richard203

any1 know? how to remove the engine filter box?

Post a pic of your engine?

richard203

D16Y7?
A wire connector on the sensor, a hose from the valve cover, and a bolt facing the firewall-- 10mm socket

I don't remember if there is a clamp around the throat of the throttle body or not. I know there is on a later car, but it's been a damn long time since I've had one of yours apart.

richard203

so only 1 bolt that is holding the box down?

ezone

The picture I saw showed one bolt facing the back, but I'm not gonna swear that's all there is. There may be at least one on the front too? Get a flashlight and look around.


I think it's only one bolt, and the clamp around the round part on the bottom. Yes there is a clamp like a hose clamp.....might be 8mm socket, might be 10mm

richard203

so theres a hose clamp on the bottom? gonna be hard to get that. lol

Flashlight....and a mirror?
