I have a 1992 K1500 with a 5.7. I recently preformed a tune up: plugs, wires, cap/rotor button, fuel filter, oil change and a PCV valve. While driving, between 1500-2000 RPM (in any gear) I feel a miss or a spudder. Any idea what it may be or where I can begin trouble shooting? I'm new to this model truck, so any advice would be beneficial. Thanks!
