This just started this week sence it has been cold. When I set cruse at 66mph about 1900rpm holds ok but if I use acell button nothing happens. If I turn it off and increase speed to 70 and set it it drifts back to about 66 67. Do I need to look for a vacume leak or a problem with the computer. Truck in my sig no mods. thanks D.C.

 

Have you had the vacuum system recall done?
Could be oil in your vacuum system.
Check for recalls here, you will need your VIN http://www.dodge.com/webselfservice/...ilForm(%27R%27)
