k1500 4x4 with the v6, 1998
starts and idles fine slow speed around the farm and out to the road is all good, accelerates to about 30mph then when i take my foot out of the peddle to cruise into town the engine/transmission stumbles or shunts.
Its in gear and the miss/stumble is just anoying but could it be some thing developing?
Oh ya, it accelerates just fine its only when i let off the accelerator.
Any clues would be apreciated.

If the problem only appears when you let off the gas, I'd be looking for slack in the driveline, maybe a bad u-joint or something worn in the rear end gears. YOu might also want to disconnect and plug the vacuum line to the EGR valve and see what it does. Does it accelerate normally? Have you checked out the ignition (wires, cap & rotor, plugs)?
Good Luck and God Bless
