V10 Running Rough
2002 F-250 SD V10 Auto Trans 140K miles
Engine ran fine until batt died. Vehicle then sat from Nov to May with no battery in it.
On start up now after install of new batt, engine initially surged at idle and seemed to miss (run rough) in gear/under load. No CEL or codes.
After a single short drive idle and running under load seemed to have improved a bit, but not yet back to what I would call normal.
QUESTIONS:
Is this simply a matter of the computer having to relearn after battery disconnect?
Will driving restore things back to where they were/should be?
How much driving/How far?
Appreciate any insights.

In answer to the fuel question, Yes, it was/is old fuel. Thanks for all the suggestions!
I am now able to report that problem has appeared to have corrected itself (w/o having added any fresh fuel) by driving it on multiple trips; both city and highway.
Have to assume that either a) the computer synched with the engine, or b) the engine synched with the computer?
The tail pipe was covered/capped back in November to keep the critters out.

The 5.4L V8 and the 6.8L V10 Tritons are about the most picky engines I have ever seen when it comes to fuel quality and alcohol content.

I would agree that the V10 engine is at best "finnicky" and at worst "high maintenance."
Since I acquired this truck in May of 2015, and during the course of putting only 2,000 miles on it, I have come to learn a whole lot about OBD codes. At 140K on the odometer I am now taking a crash course in P0171!
