Weird issue
Ok, so recently every time i start my truck it will start with a longer than normal crank then run fine for about 30 seconds and then it will go into a really lopey idle. IAC valve is also fully open during this, as i can easily hear it. If i press the gas during this idle the truck will rev up and hold a high rev (around 1500rpm) for a couple seconds and then go back to a normal RPM and continue the lopey idle. If i don't let the truck warm up for at least 15-20 mins and start to drive the truck will sometimes give no response when i press the gas pedal, unless i mash it. Sort of feels like its chugging. However it gets better as i drive it. Are we thinking fuel pump here? Or more in the direction of sensors, wires, cap, etc.

Haven't cleaned the IAC, but am about to order a new one. Not sure if plenum is blown or not but i have the parts to fix it sitting in my room. Just need to find time to do it. O2 sensors are stock as far as I know. And yes I have a scanner that reads data, what would I be looking for?

O2 sensors actually start influencing things after about two minutes of run-time. If it's fine for a couple minutes (from stone cold), and then starts acting up, yeah, good chance the O2 sensor is the culprit. If it runs like crap from the get-go, check fuel pressure first, and see what it looks like. (need a gauge, PCM doesn't know.) Should be around 49PSI at idle.
When is the last time the truck had a tune up??
Don't use generic sensor on these motors. They just don't like them. Get *Real* dodge parts.
