You mean not on the water like the picture of you comming out of a creek in certain TX event ? :Wow1:
Just giving you a hard time now

I guess I should ask, if anything did get wet to cause this problem. What would it be? Though I'm still finding it kinda odd that if the problem was indeed from something getting wet, that I would only have this stuttering problem on startup after the truck has set for almost a day at least.

Not sure but I would check all end cap of the wiring, the 02 connections, the ECU ( as Michael said for rust spots )
I mean is completely weird that you get the lean and rich codes together.
I will ho as far as checking the Y-pipe for any possibility
BTW... after I saw your pic that was the first thing came to mind, won't hurt rulling it out

Just for note: I let the truck sit longer than it usually ever does. From about 10 last night to 3 this afternoon, and this time started right up nice and smooth like it never had a problem.
Wouldn't that make it run rough at all times?
Yeah, certainly can't hurt. Most/all of my connections have previously been dialectic greased a while back, but that doesn't necessarily mean it can't happen, I know.
Also on another side note, I do have a minor exhaust leak, I believe it's coming from the gasket between the exhaust pipe itself and the manifold. Though it's been that way for some time and this problem has just come up recently.

Alright, well. I checked the ECU just a moment ago and it's about as shiny brand new looking as it can get.

Problem is I haven't thrown a code since the day I read/cleared them and posted them here. Still getting the mild stutter at start up after it sits nearly a day though.

Problem solved.
I haven't a clue why either. I did nothing. Only thing I can put money on is perhaps a tank of bad fuel?

Threw the P1171 but there doesn't seem to be any 'noticeable' changes in the way the Disco is running overall.

Alright, so now I'm leaning towards a MAF sensor problem. Just a moment ago when coming to a four way stop, during the brief moment I was at idle the RPM's dropped a little lower than they should have been and idled rough.
Though when I gave it gas once more to take of it went fine, and at the next stop it didn't have that same problem. No codes were thrown either however.

Try unplugging the MAF, and running that way. It will run without the MAF just fine. Just DO NOT use more than ~1/2 throttle like that, to be safe. It runs based on the TPS sensor and a look-up table for load values. I drove around with no MAF for a week. The reason I say not to go full throttle, is that below 1/2, the O2's will keep the A/F at 14.7. If you go over half, it'll probably go open-loop, then you're purely running on those look up tables, which were programmed by the engineers in Solihull for who know what barometric pressure and... it's complicated. Just avoid it.
The reason I suggest this, is that when my MAF failed, the truck ran fine. But mine totally failed. I had the P0102 code, my sensor was pegged low, so the computer just ignored it altogether. If your sensor is giving bad readings, but not so bad the computer is ignoring it, that might cause your problems. Unplugging it will eliminate the confusing signals, and let it run on the TPS look-up tables. If it actually runs better with no MAF, then I'd say that's your problem.
