engine flutter?

[LA97GST]

Ok I own a 1997 Eclipse GST with 2.5 inch dp into 2.5 cat then to a 3 inch cat back. I also have a Injen intake system with greddy type-S BOV. When i step onto the gas, and get into upper RPM's my engine (or whatever) kinda studders then goes then studders then goes....I'm not sure what is happening. I am going out of town tomorrow, so in a week I will read the replies. Give me some help please.
No Bashing! Please!

change your spark plugs and/or wires

Yep, same thing was happening to me, just replaced the plugs and wires and all was well.

Yup, sounds like ignition. Replacing the plg (NGK BPR 7ES) and wires (stock, NGK, Magnecores) would be a good start.
