I have an 03 2500 with the 6.0 engine. most times it will idle ok, but other times it will surge while idling. Sometimes it will stall when it is surging if i am moving slowly and take my foot off the gas pedal. I've heard the problem was with the MAS or ICV. If anyone knows what it is please let me know, i don't have money to start replacing everything on the throttle body and it seems to be getting worse and more frequent. Thanks in advance

I would say it is the Idle Air Control Valve too, to be sure you can check the resistance across the valve, take it out and see if it is bad dirty and needs to be cleaned. It could hopefully be something simple like that. Go to the auto parts store and find one of those books that has your year model truck in it and look up the sensors. It will tell you what the correct resistance in ohms should be of every sensor so you can compare it.
