Default p 0151 k1500 1997

I have a p0151 code that wont go away here is a list of stuff iv done and stats I have on bank 2
spider injector
swapped mass air
no exhaust leak
No vacuum leak
no intake leaks
new gm, plugs,cap ,rotor,wire
new #1 o2 sensor
170 psi compression on all 4 cylinders
60 psi fuel pressure with key on
new pcm
I ohm bank 2, it has same reading as bank 1
shrt term fuel trim 50%
long term fuel trim at 11.7 %

truck runs fine at operating speed,when I come to a stop after 15 sec the idle gets rough and it runs rich.

I have a hard time thinking I got a bad fuel filter or fuel pump,because its only on band 2..any ideas would be great..
