Well guys, I've tried searching for this for a couple of hours now, and can't find a solution. When I go to start my truck first thing in the morning, it starts right away but stutters and barely idles and coughs for about 2-3 seconds before it goes up to a normal idle. It does this regardless of the outside temperature. After that first start, I can shut it right off, try it again, and it'll start normally from that point on all day. It's only when it sits for a quite a while when it does that. It's not a matter of the engine being warm, or cold, because it only happens with that first start. It's fine after that and runs great all day. Do you think that it's just losing the fuel line pressure over a matter of hours and then needs to build it back up? Has anyone else had this exact problem? Thanks in advance for any help!!
