HI i have a 2010 yukon denali and i am having a problem that i cant figure out. When driving sometimes it will seem to stumble under light throttle about 1600 t0 1800 rpm. It does not due it all the time and never has it thrown a engine light. It has new coilpacks and new wires new pluggs ect i take great care of it and there is nothing that is standing out so i have no idea where to start looking and testing. any one out there having problems like this ?? Thanks

I have a 2005, 4.3l, 2x4, extended cab Silverado. I’ve been tearing my hair out trying to figure out this issue. It seems that after the truck has warmed up for the most part it will sputter like it wants to stall out when accelerating after sitting idle at a stoplight until I get to about 40mph or so then it just seems to regain all power and smoothness to driving again like nothing was wrong. Any ideas?
