I start my car, and it immediately dies. I can give it gas and it will stay running, but when i let go of the gas, it dies. It will not idle. Any suggestions?

 

Maybe a vacuum hose off. There's one right there by the tb.

Does it run smooth when you give it the gas, or is it missing?

Or if the IAC wiring connector is off, then the idle air won't open up to hold an idle either.
