My 2002 dodge ram 1500 4.7 liter V8 has erratic idling it starts out at 600 rpms and jumps to 1200 rpms and continues to do it at idle so i thought it could be the egr valve but this year truck doesnt have one

I would say either the throttle position sensor or idle air control valve or even a vacuum leak. Has the check engine light come on?
