There could be a knock sensor that is sending a false positive signal to the ECM. If a knock sensor detects engine knock it retards the engine timing to try to stop it. If the knock sensors are working good, then the timing is off and needs readjusted. If you need further assistance with your engine having a poor acceleration, then seek out a professional, such as one from Your Mechanic, to help you.
