For the last while my truck while idling, sounds like the vanes in the turbo move randomly. Normal hiss, then normal throaty idle, then back to hissing. Yesterday with about 1500 pounds payload on the truck, the truck started to buck/surge while climbing a summit, converter locked, decent rpm, egt's stayed steady, stock boost gauge didnt seem to bounce as far as i could tell, etc. Just felt like i was on and off the throttle repeatedly, then quit doing it. Any guesses? Couldnt seem to find anything searching*bdh*
thanks guys
