Try cleaning the Idle Air Control Valve.. It's located directly under the throttle position sensor. My truck would start and then die right away. I cleaned the valve with some cleaner, and let it sit over night before putting it back on, and my truck has run fine since.

ok the battery is new 2 weeks old alternator had it checked a few days ok was ok not sure now.it starts right up no problem but as soon as it starts the idle jumps up and down and then the truck stalls out.last tune up I don't know I just bought the truck a few weeks back so heck if I know but it looks like the plugs and wires are from 03 so I guess I better change them out.guess I better check the Throttle body ill buy some cleaner and some iac cleaner.didnt do anything today to it its just sitting but maybe sunday thanks guys.

Take that IAC off, it's got one screw holding it on, then put the whole can of cleaner to it. I gave it a couple hours to dry thoroughly, before putting it back on... My truck actually seems to run a little better having cleaned it off. And I was pretty much having the same problem as you...
