Question I now know why I have a vacuum leak... With PICS!

I found 2 loose hoses. I hooked 1 up n I was told 2 cap the other 1 off.. Since it goes 2 the smog. Which isn't hooked up.. When I did so the car will not start.. N when it does start it stalls right out! I un-capped that 1 hose and tried 2 start it. N it did the same thing.. I unplugged the other 1.. N the car starts up n runs!?!

Here r a few pics of the hoses n where they plug into:

The hose that I capped off..


The hose that I hooked back up..


A pics of the both hoses n where they go/come from..



Any help here would be sweet..

Thanx

well looks like all the smog stuff is still there because that tube that goes behind the motor is part of it.

get some carb cleaner and spray it around that area with the car on.

if it stills out or changes rpm.. you know got a vaccum leak.

Yes the smog stuff is still there.. But, just not hooked up(vacuum).. I'm going 2 remove all of it once I research on how 2 do it.. I do have a vacuum leak with those 2 hoses..
