Well when i first bought the truck it had a small valve tap, but i just got new ones installed. The other day i was driving home from my buddy's and parked my truck. I went back out later and started my truck as I'm giving my truck gas in drive its making this gurgling sound like someone poured water in my engine or something like that. Like if you had you exhaust sitting in a thing of water and gave it gas is what my truck is doing. I was just wondering if anyone has any ideas on what the problem might be.Thanks
