    My truck is a 2006 Peterbilt 379 with a 2005 Cat C15 MXS engine, several weeks ago I noticed that my truck when I accelerated it with the accelerator pedal started to have like a hiccup until i stopped accelerating, so when I accelerated it with the cruise control button it accelerated good and it works well so it only makes the hiccups when I accelerate it with the accelerator pedal, by the way, I already change the accelerator pedal and the same problem continues, who can tell me where to start looking for the issue?
