You prolly havea huge vacuum leak. Check for this and your idle adjustment screw on the TB. The BACV only ups the amount of air put into the UIM after the TB to keep idle strong enugh on load. Such as AC. You can increase your idle from the BACV acording to the haynes manule but I use the TB screw. ps. I have no BACV on mine. |
The black hose coming out either side of the BAC is the water hose. That nasty looking piece of red heater hose coming out of the bottom is the air hose.
If yours needs replacement, you can use a similar piece of nasty looking red heater hose, a piece of fuel line, or the proper hose from the dealer. |
i know its blurry and now im pretty sure that its NOT the BAC hose but here it is and i need one if anybody has a spare or knows where to get one
\pic |
That's your air bypass hose...
Unless it's really ripped up, repair the hole with black RTV silicone... If that hose has a nice size hole, yeah, you're gonna have a rough time idling... |
well do u know where i could get one?
|
junkyard? Hell see if you can match the diameter with some hose at a napa autoparts
|
^^ Yes, just go the auto parts store and buy some replacement hose. They sell it by the foot.
Do yourself a favor and get used to that rubber hose section of the auto parts store. If your working on a 7 you'll need about 50' in various sizes before it's all over. |
better yet, go with silicone, especially for the smaller diamater stuff
|
do you guys happen to know what size the air bypass hose is? cuase im really hatin not havin a running car lol... well it runs but then it dies
|
does anyone know the size of the air bypass hose
i need a new one but dont know what size it is b/c i threw mine away b/c it had a huge tear in it...i knew i shoulda kept it
|
can sumone plz help?
i need to know the size of the air bypass hose... it seems like nobody in here knows... can sumbody help plz?
|
what an air bypass hose. I can go measure it.
is it the one coming off the stock intake going into the throttle body? |
it is circled in this pic... i need the diameter dont worry about the length i'll just buy a couple feet of it for other stuff
Here's The Pic sorry for it being so blurry but you should be able to determine which one it is... also, i dont know if stores measure hoses by outside or inside diameter? makes sense that it would be the inside right? well if you know could you give me the right size? Thanks for helping :bigthumb: |
check what it mounts to then go from there.
