Hey guys I just solved my p0122 code and ended being a short wire by behind cylinder 5 and the firewall. After doing many test and running a live data, noticed the tps % was changing when car was at idle. As you move the wires I noticed the % increases and truck will die as pcm adds fuel but tb was closed at idle. I ended cutting the blue and gray wires at the tps and also the ones at the ecm and running new wiring and soldering them. That solved the problem for me. If someone finds this post and needs pics let me know as I took pics showing what I did to solve this code!

 

I would like some pics
