I have a 2012 ram 1500 BigHorn with 119k miles on it that I bought last thanksgiving (it had about 112k miles when I bought it), tonight when I turned it on to go somewhere it turned on and then sputtered and died. The truck wouldn't start for a moment after but then cranked up. I was curious if anyone had any idea what could have caused that? Or if anyone on here had suggestions of what a tune up would consist of before I go to the stealership and have them charge me for unnecessary stuff. I recently put a 4inch pro comp lift on it and when I got it back it feels like the truck has been driving sluggish a bit. It felt like it needed a tune up before the lift went on though, Any thoughts of suggestions? thanks!
