Removed air intake resonator, now I'm paranoid!
I removed the air intake resonator on my 97 Accord SE 4cyl non-vtec. I did so because I heard it makes the intake louder (which it did) and also allows more air flow. Anyway, supposedly there's a couple vacuum lines that ran to the resonator? I never saw any upon removal, and I don't hear any vacuum leaks but I'm paranoid that there might be a hose dangling around. This thread: NTPOG 5th Gen Stock Resonator Removal - Butterfly Controller shows there is a butterfly controller located under the intake, but I don't see one on mine? Other threads I have read through say there is a vacuum line going from the intake mani to the resonator, but I DON'T see one!!! Can anyone clarify any of this for me please? I've done so much research and haven't found my answer.

The link (North Texas Prelude Owners Group - NTPOG) is for Honda Preludes, the Accords were slightly different. Even among Accords, there were differences depending on trim levels and years (e.g., EX 94-95 vs EX 96-97, EX vs. LX, SE, etc.). On the Honda parts sites, there does not appear to be a identical shape tank on the Accords.

Here's a couple of installation instructions for Accord cold air intakes.
http://www.injen.com/galleries/produ...directions.pdf http://www.partsgeek.com/assets/perf/full/1411024.pdf I also attached a couple of parts diagrams. Note: In the attached parts diagram for the install pipe tubing, the tube running to Resonator Chamber B is not applicable to the Accord SE, only to the Accord EX (EX had the a Resonator Chamber B). |
any gain in power would be negligible, in fact you may lose some power if you just increase air flow with no other mods. put your pants i mean parts back on please ;)

So basically I DO need to cap off one vacuum line which it shows in your second link on the fourth diagram. I just can't tell where the arrow is pointing to? lol sorry for my ignorance here. Thanks for all the diagrams!

Take a close look at the part you removed for any obvious places where a vacuum hose would be attached.
What part did you remove in the pic below? Did you remove any other parts? http://www.hondapartsnow.com/diagram...ber-461548.png |
Here's another link with very clear picture instructions. Note: When it refers to VTEC only, they are referring to the EX model which had the Resonator B Chamber.

PAhonda, I removed all parts shown in your picture. I studied the resonator and couldn't find any vacuum hose nipples.
redbull, I looked back at the other links you gave me and noticed both of them state that the EX with vtec is the only one that needs to cap off a vacuum line. So theoretically I shouldn't have any vacuum leaks? Still doesn't explain why I hear a whistling sound on the passengers side but maybe it's just my intake? lol |
Do you remember unplugging any vacuum lines? If you still have the original intake, take a look at that to see any vacuum line connectors.
You could try spraying some carburetor/throttle body cleaner around different areas to see if there is a change in idle or sound. Maybe you can post some pictures of different areas of the air intake and intake manifold. |
I don't recall unplugging any vacuum lines, although I yanked the resonator out without actually looking first. I'll take some pics tomorrow.
