Intake Mainifold

[91fourdoor]

i finnaly opened the hood to try to fix my idle problem, i took the front valves off of the intake manifold and cleaned all of them, but there was still no change in my idle. i took the whole inake manifold off to see if there was anything i could clean behind it and the inside of the maniflod was dirty as hell so i cleaned it, but the intake manifold is off of a Ex accord and when i first put it on my car, i cleaned it real good, i guess this means i need a new cone filter, or can it be something else? and also i search all over but what else could my idle problem be?

First thing that popped up into my head was the IAC valve, I know you say that you cleaned all the valves but go ahead and check this out in case you missed something,

Did you clean and adjust the FITV? Check all vacuum connections. Even the smallest unplugged hole cause eratic idle. Check the coolant level and also the radiator cap. A worn cap causes bad idle as well.

Sometimes cleaning the IAC doesnt help. Sometimes you just need to buy a new unit. And it wouldnt be a bad idea to adjust the FITV while your there.

Wheres the FITV located, and how do i adjust it?my cap is worn, im going to get a new one, also, the coolant is a nasty orange color, i should probably do a rad. flush this weekend

Standing in front of the engine the FITV should be located toward the right side of the intake manifold. All it takes is a phillips head screw driver to move the steel piece adn you will see the adjustment inside. Try to get something thick enough turn it clockwise until it goes down all the way. There are two phillips head screws forgot to mention that. Plus i think its the next valve looking thing next to the IACV to the right.

I would pull off your egr valve and clean it out really good, check for vacum leaks.

but can you clarify what your idle problem is? is it rough? does it surge?

Check the link I posted above, it has pics and description and is very easy to follow.

it surges up to 3000 rpm, it gets a little higher when i hit the brakes

[brads94accord]

well then its either you have a really big vacum leak...or the adjuster screw came loose on your fast idle valve...does it surge at all? if so then you might need a new IACV (idle air control valve)

[91fourdoor]

is there any wuick way i can check for vaccum leaks?
