ok, i put an AEM CAI in my 2006 cobalt ls, and there is this hose that was connected to the old airbox (the top box) that goes down onto like a fan kinda? and than looks like it gets recirculated through out the engine, i was just wondering if i have to do something with it or if i can just take the damn thing off

skoshi130

I think that is your vacuum hose, and if it is I do believe it should be connected

NyCobalt88

what am i supposed to connect it to?.. it came off the old airbox so should i just leave it and put like a filter on the end of it or something like that?

IonNinja

a hose from the airbox? the only hose I know of connects to the valve cover

bluebaltjim

is this the hose to which you refer, if so you should have received this longer one with your cai. it simply replaces a much shorter one thats on the stock air box. hope this was helpful.[IMG][/IMG]

the hose on the top of your airbox id the hose going to the air pump for the exhaust system. The air pump pumps air into the exhaust system during warm up to assist in emissions. you can cut it down but it shoud still have a filter on it. dont want to suck in any birds hahaha . hope i helped

NyCobalt88

yeah, thats gotta be it ted, thanks alot man, so i can take off the big plastic end and put a filter on it? but im disapointed in AEM when i called to ask.. i guess they dont have a model out for the 06 yet, so the one i put on was for an 05.. and the guy who i talked to was a real jerk.. he was like nah we dont have a product for the 06 and than he hung up on me.. oh and by thee way when i took of the spalsh guard to install the CAI that pump was only being held on by like 2 threads on one bolt, one fell out and the other was was about too.. luckly i caught the last 2 on there last threads..

ted5986

yeah just pop a filter on it or cut it all the way down near the pump. just as long as there is a filter you'll be fine. glad i could help .

i now have a CEL on.. and the computer the guy put on at auto zone said system running lean, is there a way to riched it up, and make trhe light go away??

throw money at it


you can disconnect the battery for a bit it should clear the code ..or get a 25$ code reader/clearer from wal mart ...

it might go away on its own when it gets used to the new fuel map as well

ted5986

actually just to let you know, the code reader/clearer from wal mart or from any store will not work with the cobalt because it doesnt use the OBD2 system like everyone else. damn technology. our cars use the lan system . only thing that i know of to get rid of that light is unplug your battery for 30 minutes and let the computer forget its adaptives. if that doesnt work....dealer??? thats my $.02 sorry

bluebaltjim

this also happened when i put mine on, i took it to the dealer and they had it in the back for about an hour. when they brought it out the cel was off and has never came back on(two months). they said that if it came back on i should reinstall the stock airbox or i could have issues with the warranty. i checked my file on their website and it doesnt even list that i ever took the car in. my best advice is disconect the battery and let the computer reset and learn the new setup, im pretty sure thats all they did.

Do the Cobalts ECU, can it even 'learn' Does it have on board RAM or some sort of flash? Why would a batt unplug reset when turning car off not, meaning why doesn't it adjust on the fly for this sort of conditions?

this is what i dont understand...i have an 05 and i have that hose, so i dont understand why you wouldnt have it on your 05 AEM filter.

i see this is a couple days old now, did you get it figured out?

NyCobalt88

yeah i did civic, thanks its a 2006 and its an emmisions hose on the airbox for cold starts, not the breether hose
