Hi everyone, I have a 97' ram 2500 5.9 360v8. Trucks got like 200k on it. I just had the tranny rebuilt like 2 weeks ago. So today i stopped to get gas. after i fueled up i started the truck and the tack shot up to 2000rpm and wont go back down. Its revving high constantly while driving and around 1500-1700rpm. I turned the truck back off and on and every time its in park or neutral its still revving and sustaining at 2000rpms. I'm scared of blowing the motor and/or transmission and i know it def. cant be safe to drive like that. I checked to see if maybe the throatle cable was broke or stuck and its not. I'm TOTALLY lost on this one!...Anyone have any idea what could be the cause and/or how to solve/diagnose the problem??? any help would be much appreciated!
