Possessed Excursion?
Really confused....my x started acting up Sunday. Was really damp/foggy, temps around 45f and a lot of snow melt in the air. While driving, the x started bucking and shaking when accelerating from anything over 40 mph. Also had a random missing sound to the exhaust, but nothing consistent, and exhaust smelled bad. So I topped off the tank with premium fuel and a bottle of fuel additive. Drove it around trying to get it to work out.....no luck. Also, no CEL! Tried reading codes anyway, none. Changed fuel filter, checked plugs/connections, nothing unusual. Drove it 13 miles to brother's shop, ran same and actually died as I parked in his lot, but started right back up. This was all Sunday. Monday evening as they were getting ready to close up, his shop kid went to pull it into the shop and couldn't keep it running! Tuesday after sitting in the heated shop the tech took it for a drive and it ran perfect! They then left it outside Tuesday night and same tech took it for a drive today and it ran perfect! WHAT THE HELL! I was planning on taking this to the cabin Friday morning, now I'm not sure I can trust it
Any thoughts, could it have been the moisture in the air? Sorry about long post, just trying to be thorough!

Spitting and bucking is either a fuel issue or an ignition issue!
So did they put a scanner on it and look at live data? Did you check the fuel pressure?
What did the exhaust smell like? Rotten eggs? It is possible you have a CAT going bad. If it acts like that again you could drop the cat and see if it runs better.
I had a car that I put an engine in for a buddy. The original engine toast 2 cylinders. I get it running and it acted the same as with the old engine. I dropped the exhaust at the manifold and it ran great.

Those codes are elusive, sometimes they do but often they do not. Just have to catch them in a "snit moment" and start unplugging to find the offender.

I second the extra CP and ratchet 
also might want to familiarize yourself with the engine bay before the trip too if you already haven't. You're pretty new here so I assume you don't know how to pop the hood, it's the latch next to the left leg on the drivers side Seriously though, I would bring a CP or 2 with me, you never know, 2 could be bad...

Just an update....took the x on the trip to the cabin, 400 miles with zero issues! I am guessing because of the damp weather last weekend, something got wet, then froze up and thawed/dried out while in my brothers shop overnight.

I used my torque app/blue tooth obd adaptor to find the coil packs that were miss firing on my 03 V10 work van.

True but with torque you can see the number of misfires at each cylinder.
