`01 SC1 throttle lag

I have a 2001 Saturn SC1 with the SOHC 1.9L. When hard accelerating in second gear, the engine boggs down at about 3300 RPM and does it again about 4200. It does it for a split second. Enough to drop about 300 RPM. It only does it in second gear. Has anyone heard about a possible ECM programming problem, or anything else from the factory. The car is bone stock. PLEASE HELP!!
