I just purchased my first truck this last weekend and I am very pleased with my purchase so far but I have a (hopefully) small problem to sort out. Truck it a 95' K1500, 350 5spd. manual. When decelerating in any gear the truck will jerk relatively violently. It dosn't happen all the way down the RPMs just right after I take my foot off the gas. It almost seems to me that maybe the 4x4 is trying to engage but the light doesn't come on and the lever is firmly in place of 2wd. I am at a total loss as to what it could be. Any help would be greatly appreciated and if you need more info to diagnose the problem I'll do my best!
