2005 Yukon Denali with ~200,000 miles on the 6.0. I'm not driving this truck as much anymore, so when I start it, she's dead cold. I get a big "snort" sound on startup, almost like a piston is pushing air back out the intake. It goes away after the engine is running, but I'm wondering if it is a sign of a bigger problem.
