I own an LT 05 tahoe, 2wd with the 5.3 vortex. This only happens when I give heavy acceleration from a stop, until around 25 mph it bogs or "trips over itself". If I lift the pedal about an inch from the ground I feel a gain of power, even tho im lifting off the pedal. Once I reach 25, everything seems normal. I just recently went around unplugging my ignition coils one at a time too make sure none of them have gone bad, and every coil shows a decrease in rpms when I disconnect it from the motor. I have thought that it might be my knock sensors causing this problem, as when the engine is cold and under heavy acceleration you can hear a distinct ticking, or sounds more like if you shoot air from a compressor through a fan while it's on. If anyone has any tips or fixes, I'll be glad too take em.
