Belching out intake

[grnadnasty84]

when i start my GN and it is cold it idles fine but when i try to move it starts to pop out of the intake. this only last for about half a mile but it's really annoying and i thought it had to do with the vac lines but i cant find any problems there. if anyone knows what it might be that would be greatly appreciated. -thanks-

Running lean most likely. Check the temp sensor first.
