Vacuum Leak?
I have a problem a with surging, but this one goes away after warming up. When i first start the truck, it runs for about 2-5 mins before it starts surging. Less if i am driving it. (Doesn't surge till it reaches a certain temperature.) Then while it is surge prone, if i brake, the truck surges at a lower rpm and faster. Although, when the truck is at operating temp, there is no surging at all, brake or no. I am not sure if it is a vacuum leak or a temp sensor or a tps valve or what. If someone else has had this problem or know what it is, please help, because i am embarrassed to warm up my truck and have it revving in the background.

Mine use to do the same thing, among other symptoms that hit the truck at the same time
