so this just happened for the first time today... I was backing up into the garage and when i put the truck into reverse the rpms started going down and then eventually it would stall at around 200 rpms.. But when you give it some gas in reverse its fine.. it only happens when you don't give it ny gas... This just started happening today and it only happens in reverse... Wut is wrong with my truck??

 

Bump the idle up. mine did the very same thing when I first bought it.

Heres how: Ram Diesel Problems
