gsr sputtering/ rpm goes crazy

[CautionMeDC2]

So iv been having this problem for over a month now. The engine came out of my other Gsr which I sadly rolled going to work one morning. Anyways I swapped the engine and it was fine at first for around a month. I ran an 06 Si going home from the mall of ga, as soon as i got off on my exit when I tried to take off it sputtered a bit till I got into third. Its been happening more often now and just yesterday noticed my rpm needle was bouncing alot. Any ideas? Since the swap iv done two oil changes and replaced the plugs and wires.

I work third shift so had no time to go to the parts store but did check under my hood and noticed my dizzy cap was broken. Ill be buying a new cap and rotor tomorrow. Thanks for the help and I'll let y'all know if my problem is fixed.
