My truck has started hesitating in the last few months mainly at part throttle. It seems to be almost non-noticeable some days and much worse during other days. Strangly it doesn't do it during cruise control operation, but only when I use part throttle to maintain speed. Truck feels fine during wide open throttle. I currently have 155k on it and have the mods listed in my signature. What culprits should I look at to eliminate this problem.
P.S. I pretty much run in the 120 hp setting of my chip all the time and don't really beet on the truck that much. It will throw a light and turbo surge during wot for extended periods of time at higher speeds, but other then that there is no lights thrown when it starts to hesitate.
