Alright guys, I've done some searching around but can't find any real good information. My daily driver is a 2007 Chevy 1500 wt with the 4.3 vortec v6. Whenever I cruise around 1200-1500 rpm giving it light gas to maintain speed it bucks and jerks like it is misfiring. If I let off the gas or give it more gas and change gears (automatic) it runs smooth. I change the fluids regularly and just swapped plugs and cables about 1500-2000 miles ago. What little information I have found has said either ignition or that the torque converter is locking/unlocking because of crappy shift tuning from the factory. I would like some input before I take it to a shop and get their head scratching at $75/hr.
