I have an 08 dodge ram and it accelerates ok in the beginning of takeoff but then when i let of a little and go to accelerate again sometimes the rpms drop to about 1200 and it is almost like its sputtering. is this a fuel problem......maybe my pump. Please Help, I am lost.

 

Are you backing fully off the throttle and then slamming it down? Also, is this the 5.7? How long does the RPMs stay at 1200 after you give it some more gas? Does it feel like its lost power after backing off the throttle and giving it gas?

 

It is the 5.7..... it stays at 1200 until I let off fully again and press it down again. It just sometimes won't accelerate without sputtering and it's annoying.

 

Tune up first.
Could be as simple as spark plugs
