When I crank the truck after a minute or two you can hear the truck start to suck air and it sort of stalls out while parked. But when I tap the gas once or twice it very very seldom happens again until I turn it off and it sits for little while. Then I have to repeat when I get ready to drive it. Is it a vacuum lines issue?

Hello,

Usually a vacuum or intake leak will cause either a high revving idle or a "searching" idle where it will rise and then drop repeatedly. If you are having a stalling idle, I would suggest looking at your vehicle's Idle Air Control valve [IAC]. Here are a couple of links below that will explain both conditions to you in detail and how to fix them:

Please go through these guides and get back to us with what you are able to find out.

Thanks,
