Rough idle, Stalling. Please HELP!

[jeenyus]

I just recently bought this 84 SR5 that wasn't running when I first picked it up.

I replaced the starter and changed the oil as it smelled strongly like gas.

Now to keep it running I have to keep revving it. It stalls at around 1000 rpm.

Here's the most suspicious cause that I can find. This isn't my car. It's a pic that another guy sent me. The hose labelled "Disconected" had a bolt stuffed in it and was taped up with hockey tape when I recieved the car.

Really, what I'd like to know is what this hose conects to and if it (being disconnected) would cause such problems.

Please let me know what you think.

Thanks.
