well my reading said front bank1 02 sensor its brand new?

 

Maybe the wiring is messed up going from the sensor to the motor?

On a side note, her idle seems to be fine, but she does " hit a wall" so to speak @ 3500rpm. Her car threw TPS and o2 sensor codes.

Your car should idle fine without the o2 sensor however... but I think your "wall" problem comes with that sensor. Do you mean it won't rev above 3000RPM just driving around or just when your stopped?

 

probably check O2 wiring...
hmm, maybe try disconnecting O2 and start the car? see what happens

 

Here's 2 things for you.

1. Get your MAF wiring looked at by a professional somewhere, you definately have an issue there.

2. When you put in your new headers and exhaust, where did you locate the 02 sensors EXACTLY?

Sounds like you are both going into LIMP mode.
