Symptoms indicates a misfire and it could be due to a bad spark plug wire, distributor cap, spark plugs or rotor. Under normal driving conditions, the misfire does not occur but when accelerating hard, it would misfire.

Check and ensure the spark plug wires are securely atached, both at spark plug and distrbutor cap.
