Hey guys new to the site, absolutely love it! My truck will stumble when i accelerate and is most noticiable on the highway, it runs beautiful while cruising but stumbles pretty bad when you acclerate, towing makes it alot worse, with the comp turned off its not nearly as bad. Thanks for any input.

 

i think i figured out how to get my signature on

 

mine does the same thing also, try cleaning the map and iat sensors, it helped mine(still looking for the answer). have u checked your fuel filter, fuel pressure(gauges), any codes?

 

i just did my fuel filters yesterday afternoon because one they needed it and two they gelled up and truck wouldn't start, over the summer i had a couple dead pedal situations that tripped a code for the map sensor, i replaced it with a new one from cummins problem still occured but not as often haven't had it happen in quite a while

 

ya need to take your truck down to auto zone and have the codes pulled. or maybe you have a buddy with a 2nd gen smarty?

 

ok i just borrowed my friends scanner and it read a p1693 he didn't have the book for it so im not sure what that means.

 

fuel pressure!
get it checked thats probably part/all of the prob.
i had the same prob search my posts!
