F350 5.8L Wont Idle!
 

i have a '94 f350 with a 5.8l that will not idle unless i give it pedal.
i can start it runs very low but i have to keep my foot in it or else it will stall.

also, every now and again when leaving from a full stop i wil give it gas and it will almost die, then kick back up. hesistation i would call it.

and input would be great

thanks in advance
