ok waht the hell is pressure regulator cut off solenoid valve? lines 12 and 1 are going to it. my stock 90 crx si didnt come with one. nor did my old 89 crx si.
i have a b16 first gen in my crx. growl i need to figure this out. my car fuel bogs at 2000 rpm plus. not at idle. so its not o2 we think, were thinking vacuum..
my car runs fine. but i am afraid, since line 12 is wide open, if i plug it it dies at idle. and line 1 goes to the bottom fo the purge cut off valve..

any help>?? why the crap dont i have this cut off valve thing? and my car runs better. but i think it could be faster. we vacuum timed it and it seems ok i guess. sorry i am not that technical just a wrencher trying to trouble shoot.

p.s. i cant even find line ten. there is no opneing in that part of my intake manifold.

stockcrx

any b16 owners that can help?

Line 10 doesn't exist on all B16 IMs. Personally I think that diagram is neat to look at but it's nothing like what I have underhood (yes I also have a B16A). I won't tell you what I've done since my car idles like crap, but if I ever do get the correct way to route the vacuum tubes figured out be sure I'll post it

download my manual , copy it in to a folder, i have a vaccum diagram in there.

That diagram is wrong.
The yellow and blue lines on the left are backwards. Other than that its ok.

Also, if your not worried about emissions,
then you only need 2 lines. One for the map, and one for the fuel pressure regulator. Thats it. All the purge valves are just for fuel vapors.
But you might as well hook everything up properly anyhow, since most of us dont
like the smell of gasoline in the cabin. most of us.

im not saying that youre wrong in saying that but on MY car if you reverse the 2 lines you mentioned.....it wont idle worth a crap

slowpokesi

check out my diagram its correct, download it up above

rioninja

The diagram is definatly wrong. The big port on the top of the TB is made to remove charcoal cannister vapor, and does not lead directly into the manifold.
The smaller correct map sensor port goes directly into the vacuum source. If you remove your TB you can see the difference.

I would suggest you try to find the source of your idle problem instead of incorrectly hooking up the lines.
What kind of idle symptoms are you having? Idle problems are easily fixed if you just follow a few steps.

most thank yous for all the help. i dled the diagram. so i shall be vacuuming correctly soon.

again thank you honda tech. for being ichiban in mybook.

stockcrx

also i dont have that pink hose thing. the metal part? it broke during shipping. i was told i dont need it. so i dont have it going to my intake. good or bad?

stockcrx

WTF@@ it was fuel bogging really badly before. then i fixed my vacuum problems. ITRAN GREAT FOR THE FIRST TIME!!! i was soo happy. then today when i was just starting it, the damn thing started fuel bogging again. i dont understand why this is? anyone? anyone?

Heres a few pics of mine. No codes no bogging.

Sounds like you have the O2 sensors connected backwards.....
Very very very common

Double check your O2 sensors....
What wiring diagrams to you have ??
If you hooked your original round connector to the B16A round o2 sensor. And then ran a extra wire..... you did it wrong switch them and see what happens

cheers
email me if you need diagrams etc.... I have UK manuals for B16A

T_Rex

Good pics Thanks.

it idles fine...... why am i going to mess with it?

rioninja

because you said that it only idles fine when its hooked up incorrectly.
If your happy with that, then by all means leave it alone.
Most people would rather have it hooked the right way.

eraser

DOH on me.........i went out and checked it......either i didnt trace the hoses right on the pic or something......cause they are hooked up the other way...doh doh doh on me sorry man on myself

stockcrx

so let me get this straight. i might have my o2 sensors switched aorund? alright. but why isint my ecu throwing a o2 code? also why does it only do it when my car warms up> good INFO KEEP IT COMING!!

stockcrx

p.s. i am using the 90 crx si wiring harness with the hasport wire kit. if that makes any difference.

stockcrx

ok my o2s are NOT switched around. they wont plug into each others wirign harnesses, ones green, the others grayish cream. so ..... also i have the stock exhaust manifold, so the o2s were not switched around...anyone? anyone?

spettinger

he is saying that you may have the 2 pins on the ecu switched for the O2 sensors. i made this mistake once and the car hesitated a lot, no real idle issues.

slowpokesi

my car was boggy after my swap but my plug wires were shitty, so i changed them, the cap and rotor (things you should of changed anyways)

stockcrx

yeah i changed my cap rotor, water pump, timing belt, alternator belt, plugs, plug wires, fuel filter, air filter, oil pan gasket, upperhead gaskets, vacuum lines,

stockcrx

if i had the two 02 pins switched, would this throw acode? cuz all i am throwing is vss.
