the last time I solved this problem, it was carpet under pedal)
Ok, check voltage output of gas pedal sensor. Over 4.4V is 100% -
Make sure you put the throttle pedal sensor in that your VIN calls for. Cats need a different throttle pedal than a Cummins.

it's a cat sensor it reads this with the pedal out of the truck to got the sensor from international

There is no adjustment to the throttle position sensors. Your percentage readings do not mean it isn't getting full throttle. If you changed it for a power problem that was the wrong thing. If the TPS goes over 100% for some reason it will shut the fuel off and back on so fasst it will make the truck act like it has a miss.
Mykhailo Thanks this. -
Back when I had a n-14, I had to turn key on with truck not running, push fuel pedal down and release 3 times to calibrate. Not sure if it is the same for cat but it won't cost you anything and let me know if it does work for when I replace mine
tufftimestrucking and dadddymills Thank this. -

Ouh, I wanna tell you that all new Cat ECMs read 80-90% with pedal to floor and over 80% is a kick down power, so let the truck keep running.
