I have a 1990 B18a and was wondering what this stuff is. What is that circled in the green? And then what is in the pink? TIA

I think the green is sumthing with the t/b. im prob wrong.

 

actually the green is soemthing to do with the throttle body, but what it is idk, i jsu know it came on a b17 throttle body i ahve

 

I feel so smart now.

 

I'm not sure on the exact name. But they are vacuum solenoids meant for OBD0 ECU's. A lot of 'em are left disconnected.

 

So I don't need either one?

 

bump cause I have these on my b16a 3 years later and still don't know what the hell they are.

 

try cruise control retards

"hi my name's mike, did someone ask a question? I probably don't know anything but look at that pretty 'post reply' button [*click*]"

OBD-1 integras came with the one on the left, for cruise control. b18b ls motor, see how its something connected to the throttle body butterfly other than the throttle cable, lets think of what other than your foot affects throttle by way of the main butterfly.

not saying OBD-0 didn't come with it, but not ONLY OBD-0

edit again: solenoid = an electrical device consisting of a wire wrapped around in circles commonly surrounding a magnet, electricity goes through the wire, a magnetic field forms, the magnet moves, like pinball paddles, those are solenoids, vtec solenoid.

vacuum has nothing to do with solenoids.


any more non/mis information

 

Im thinking they had to do with automatic tranny as both engine came with auto trannys...

 

possibly the center one, but the one on the left IS cruise control

 

the one in green is a throttle damper. when you let go of the gas, it returns the TB to the fully closed position slowly so the car doesnt stumble. the one in purple..i forgot.

 

bump cuz i'm interested too...

Hey retard, it's not the cruise control!

The green, well, Honda calls it the dashpot diaphragm, and it has nothing to do with the cruise control. Or an automatic transmission.

The pink is called an air boost valve.

Look in the factory service manual for a 90-93 teg, both are fully explained.

Both of these are designed to prevent a rich/lean condition during abrupt throttle changes. OBD-1 ECUs solve this problem electronically, not mechanically like the older engines. OBD-0 D16A6, B18A & B16A have these devices.

Question for EGmikeH22, My 94 Civic has factory cruise control, yet it only has one throttle cable atteched to the butterfly, and nothing else. How does it work?

A: The cruise control cable is hooked up to the gas pedal, not the throttle body.

 

OBD-1 b18b has it, cruise control, ask nsxblueteg for pics of his motor (93 ls).

or did i just get owned? anyone else?

you got owned, and not only owned, but you look retarded telling other people mis information while bitching about people giving misinformation.

the dashpot on the throttle body makes the throttle not close abruptly when you jerk your foot off the throttle. its supposed to prevent jerking and a lean condition when you suddently release the throttle. the air boost valve (pink) assists in cold starts.

and secondly, 93 integras have a B18A1 OBD1 and not a B18B1. the b18b doesn't have any provisions for either of these.

 

well I just thought it had something to do with automatic tranny because I have 4 other OBD-0 pr3 intake manifolds and they are all sealed off at the location of the pink circle. Oh well. Thanks guys. The pink one is now disconnected due to it causing a vaccuum leak. Idles much better now
