Default Dakota overfueling issue

I have a 2000 dodge dakota 4.7L, AT that has an overfueling issue. I had a programmer on it, when i took it off the the truck started running rough. I replaced the upstream O2 sensor. The local dealer put it on the scanner for me to make sure that was the only problem. It worked for about 2 or 3 weeks then it started acting up again and i replaced the o2 sensor again under warrenty. This happened 3 times total. After the 3rd the dealership then took it upon them selfs to scan the truck, then 3rd time of replacing the o2 sensor they had started pulling the P0171-1/1 FUEL SYSTEM LEAN code. I got the print out sheet with all of the possible cause of the problem and with out spending outragous amounts of money their is no easy way to find out the problem.

when you removed the programmer from the truck did it uninstall itself completely? i've seen some programmers not completely uninstall itself due to a low battery and cause the computer of the vehicle to crash. basically causing all sorts of problems.

the programmer screen said that it uninstalled. we put the programmer on 2 other trucks since then also and it has not affected either one of them. What would be the best bet on fixing this problem. i have already left the battery unhooked for hours to no success

dodges do not like power programmer, thus why it voids the warranty on them, I have heard of people having nothing but problems with magnum/hemi motors and programmers, cummins, however, will love the programmer, till you remove it, then, they fukc up like the other motors.
In other words, keep the porgramer away from your Dodge.
