Starts but won't stay running

I have a 1995 ranger that starts but as soon as it drops down to idle speed the engine dies, other wise I have to keep my foot on the gas. I have tried cleaning the IAC, the throttle body, and I changed the fuel filter. I am stumped as to what else this could be, especially since it started doing this out of no where. Any suggestions would be appreciated.

alright, Just one of those simple things. Id start on fuel pressure maybe? does it fire up fine? and then just die off if you dont feather the gas?

Yea, it fires right up but if I don't keep my foot on the gas then it'll die. How do I go about checking the fuel pressure?

There should be a pressure relief valve under the hood on the fuel system. It will look like a valve stem on a tire. for quick bursts ive used tire gauges to read pressure. not the best but it gets it close enough to have an idea what its at
