Alright so I got a surging problem. It's pretty bad. I used a scan tool and I saw that the tps stayed at 0%. So I went to the tps connector and there are pins on the harness side but in the tps itself there is absolutely nothing. Is there something broken or missing? This truck has me confused and I just can't figure my surging problem out for the life of me

Alright so it's a 04 early model. It's a 6.0 obviously. And I think I have it narrowed down. When cold it surges pretty bad but when I drive it hard for a few minutes the problem disappears until the next cold start

Is it a surge as in the RPMs go up down with out any pedal? Or a hesitation when you gas it? What oil do you use? It could be stiction- Inj that are sticking how's it run when it's warm?
