Default 2007 2.5S hesitation problem

I have a 2007 Altima 2.5S with 181,000 miles on it. I recently changed the fuel pump as I was having a hesitation problem at low rpm only. I also changed the CVT fluid while I was at it. In addition to the fuel pump, I added two cans of BG44K fuel cleaner ( one can per tank of fuel) and I still have the hesitation problem. I have also replaced the coils/plugs and valve cover prior to this problem and did not experience this problem until sometime after. Any help is appreciated

Well, I found the issue... The wires going to#4 cylinder had become bare. The insulation was brittle and broke off causing it to short out the coil. Fixed that and the problem went away.
