Engine Performance problem
1990 GMC Truck V8 Four Wheel Drive Automatic 200000 miles
1990 gmc 350 5.7 it runs rough at low rpms in gear in park or neutral it runs fine and smooth but when I first put it in gear it sputters like it is going to die almost as though it is getting too much gas or to little but I cant say for sure I have changed the oil several times I have also tuned it up with plugs, and wires, and rotor and cap. I have also replaced the fuel filter and air filter. Im extremely frustrated please try to find a way to help thank you
