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.
