Car will not stay running unless using accelerator?

What is your question?

I own a 04 Jeep Grand Cherokee, less than 90k miles on it. New battery replaced as well as starter and spark plugs from the following year. The vehicle will not stay on/or run unless I have my foot on the accelerator. Tried using a fuel injector cleaner and ran the vehicle for 15 minutes but no luck. As soon as I removed my foot, the engine shut off. No check engine light present. Thinking its the IAC? Thanks for any help.
