Sounds like a misfire. Recommend replacing tune related components. Spark plugs, wires, cap, rotor, pcv and fuel filter. If has no cel then may need these if are old enough. When remove plugs you want to see them all burning the same. Look for deposits that can foul out the plugs. May cause the skip again quickly if is burning oil, fiel fouled, etc.
