Smooths out immediately upon acceleration. Smooth idle in park. I’ve changed plugs, wires, PCV, distributor cap and rotor, coil pack. Compression check all cylinders. Inspected for vacuum leaks. EGR Valve replaced. Have not replaced distributor yet. Not rebuilt carburetor yet. I’m at a loss why it shutters only sitting still in drive and not when in park. Thanks for your help.
