It’s not an idea
If it is your tps that will tell you if it’s bad or not.
Same logic as having a misfire and swapping coil packs see if the problem follows the coil pack. Then you know that one is bad, save you the trouble of having to ohm things out or back probe.
Same thing happened to my truck
And I did all the same exact things you did
I even went as far as replacing the iac and the maf just cause I had a parts truck.
Not until I look at my live stream data I could see my tps voltage was all over the place. I unplugged it turned the truck on truck was perfect
Swapped the sensor with one off the parts truck it’s been fine for a year now
