seems like its holding in high gear thinking its at a higher pedal then it actually is. again scan all your sensors for normal range of operation.
Agreed, that was my 1st thought..

It's pretty simple to test:
Take a paperclip and backprobe the connector going into the TPS, you're going to need to know which is the signal wire.. try the middle one 1st.

Use a Voltmeter and move the throttle with the car keyed on ONLY. It should be 0 at rest and 5v or just under(4.8/4.9) at WOT. You can test for deadspots or issues if you slowly move the throttle and notice a dip in voltage.

Repeat test with the car RUNNING and see if theres any spikes, or dips or anything. If the TPS is the problem you'll find it doing it this way.

Would be awesome if you had a scope or a graphing multimeter though lol
