Hmmm, did someone mess with the throttle plate?

hmm.. what do u mean? I fucked with it forever today and tried to get it as close as possible and then stuck it in the car and the safc is still reading the voltage different then what the multimeter read but whatever. Ill just see what it does when i fire it up.

[carotman]

Well, you're not supposed to touch the throttle stop screw. you have to set the TPS fortage by adjusting the TPS, not the butterfly.

[newaccorddriver]

out of curiosity, do we still use the intake manifolds bracket that sits underneath?

[gfrg88]

nope, the new IM sits higher

[newaccorddriver]

is that little bracket actually needed in the first place? even for our stock intake manifolds?

[gfrg88]

i dont see why we need it, that bracket is bolted down to the engine so it doesnt make a differnce....

[newaccorddriver]

wouldnt it relieve a bit of stress off the head studs cause it doesnt let the manifold vibrate as much?

[adams86lxi]

Hey so ive had my car running on the b18 intake mani for about a week now? The only prob im having with it is the fact that the idle is rediculously low sometimes.... WTF could cause this. I have the idle screw all the way out and its still really really low sometimes. Not all the time but sometimes?

[adams86lxi]

?

[newaccorddriver]

i think it might be the fast idle valve. i just turned my idle down today through that thing from 2300rpm to about 1200rpm. just gotta use the adjusting screw now. but id try adjusting that thing if possible though

yea, thats the only thing i could think of too. Ill have to try adjusting it tommrow.

[adams86lxi]

well tried to adjust it today. It doesnt seem to adjust like the a20 ones do or something. All i saw was alittle nipple thing once i took off the cover for it. I tried turning it but didnt seem to help my idle at all. It still idles really really low i mean like at 400rpms or so. I dont even know how it stays running lol.

[reanimator420]

well its quiet ya knowlol

[newaccorddriver]

try asking people on honda tech, they might know more

[AccordEpicenter]

did you connect all of your vac lines correctly? Make sure your distributor is getting vaccuum

[gfrg88]

well its quiet ya knowlol

actually its extremely loud, its awesome

[B16KILLA]

actually its extremely loud, its awesome

I agrre when I heard that car come up the street, I creamed my pants.
She is so SEXY!!

[Versanick]

With as little running as my motor has been with finally the BLOX b18 manifold, instead of sounding like a cool honda, it sounds like a full race car.

The mani is like day compared to the night of the a20 manifold's 90 degree bend and comparatively poor design. I highly reccomend.

Adam, I had this idle problem last year when I installed my Edelbrock manifold. Can't blame you for not remembering

https://www.3geez.com/forum/showthrea...ight=edelbrock

Basicaly, the B series TB idle screw inlet hole is too small for our engines.

Remove the TB, remove the screw and drill it out to the A20A size.

[carotman]

So, did it work?

[gfrg88]

im thinking of getting a civic front strut bar and moding it to make fit on my car, but i remember someone said, i think it was carotman, that with their b16 intake manifold their strut bar didnt fit anymore. does anyone else now if itll fit????? q

[MessyHonda]

he has another Intake...Edelbrock Manifold?...well if you are going to mod it just make it clear the intake...just dont make it hit the hood when you close it

[carotman]

Well, with the delbrock manifold the DC strut bar clears without a problem (better than with the A20A)

I tried a B18B intake and it didn't clear the DC bar. thegreatdane also reported that the B16A intake manifold didn't clear his DC bar. (https://www.3geez.com/forum/showpost....9&postcount=15)

[gfrg88]

thanx for letting me now. another quick question does it barely hit the manifold or does it hit it by a lot?? do you think i could somewhat use some washers to make it clear it??

and also do you guys think that this strut bar will be close to actually fitting the car, or is it from another year civic??

[carotman]

There was no way it would fit

Maybe a different bar would fit tough.
