Got a new tps (was throwing a code for low input voltage) however, its sluggish until about 1100rpm, then it picks up a little, then around 1900, it picks up a LOT and smooths out a lot. It wont shift until 2500rpm or around there. Through all gears. No overdrive. No kickdown gear. Also, in certain spots, I will have almost what seems like a slight misfire, usually around 45 mph or 50mph, almost like a dead spot?

With this year, the TPS is just slide it straight in, bolt er up, correct? I dont have to line up the shaft on the throttle valve so it catches the teeth on the TPS?
When installed straight, I have the symptoms stated above in the original post.
But when I line it up to catch the teeth, I have the same power issues (smoothing out around 1900rpm) except it wont shift until 4000 rpm.

Also when installed straight on, I don't get any voltage.
When installed with teeth catching, I have good voltage.

I unplugged TPS and it runs exactly the same (shift at 2500, no kickdown)
I did not have any shifting issues or anything with the old TPS, however I do not have it to put it back on and test it to see if I maybe just got a bad part, the old one being good and it being an old stored code. (no CEL, previous owner disabled it)
This is going to be the death of me, I swear. It is driving me crazy!!!

Did you adjust the TPS?

No adjustment on 91-01 throttle position sensor.

Where did you buy it? It isn't really that unusual to get a bad one out of the box if you buy aftermarket.

said "screw it" bought a new one.

turns out it was a bad one anyways....
