o.k. so here is my deal that i have not been able to figure out. my truck bucks and kicks only in o/d from 50 to 60 under light throttle. if i mash it, it will shift into o/d around 55 58 real smooth with no bucking. it totally goes away when the rpm are up. this started right after i put my ddp stage2 75 hp injectors in about 3 months ago. never did it before the injectors. question is could it be getting too much fuel down low in o/d? not smoking like a freight train either. how can i correct this and has anyone else had this happen? thanks alot!!!!! p.s tranny is fine and have a new tps.

 

have you tried adjusting the tps correctly?

 

well i did knock the metal pins out and rotated it. did not drill holes out. thought that it is a new tps that is should be fine. my old one with holes drilled out was only getting .65 volts at wot. what would be the correct tps adjustment? thanks!!!!
