Repost-Low RPM/Weak acceleration

[JoeBoxer1130]

2004 Grand Prix 3.4
So I can?t figure out what?s wrong with the acceleration for my vehicle.
For some reason in some times the engine takes like about 8 to 10 seconds do accelerate. It feels like there's no fuel coming through. Eventually it works after a few miles and doesn't do it as often. But it is an issue that I'd like to fix, If I tap the gas pedal a couple of times feels like it throwing the shifts. But there's no problem with my tranny. Times this doesn't even happen.
I have cleaned the throttle body many times but obviously that's not the issue.
Any tips or help is greatly appreciated.
Thanks in advance.

Turns out the cause was the oxygen sensor in case others have the same issue.

I would think if it was an 02 sensor issue, you would have been getting a c.e.l.......not mentioned on op?

Yeah. As soon as I unplugged the O2 sensor the engine was smooth. No rough idle until I connected it back. Didn?t show up on my scanner to check it before.
