Default tps throwing cel on hard acceleration

So long story shortened a bit, I swapped a different head on my motor and when I had the IM off my wife accidentally dropped it, and the casting broke where the throttle cable bracket bolts onto the throttle body. I have a s2 IM so I just went out and bought a type r cable and bracket and installed that and its been driving flawlessly...minus one thing. Only problem is when I really lay into it, red lining each gear,the CEL comes on and stays on until I shut the car off and start it back up. Every time I do that it goes away and I even had to pull over and jump the harness with car running to check the code. Its code 7(Throttle Position Sensor) If I just accelerate hard for a couple of seconds and then let off it doesn't come on, only when red lining. Now the only drivability issue that results from the CEL is when I come to a stop my idle is high, like 1.5-2k rpms. I've tried to research and alls I can come up with is people having hesitation and bogging issues resulting from this code. Anyone have any ideas? Thanks for any and all help

I'm thinking the sensor has a short in it, and while accelerating, the sensor reaches the short, cel comes on, and the sensor keeps rotating which keeps the car going.
Replace the tps sensor.
