What Does This Code Mean?

[Hickfied]

I can't figure it out..
341 Octane jumper installed (information only code to notify you if it is installed)

That, along with a code about my disconnected EGR, PS pump, EVP canister, and purge valve are the only codes I get. My car idles fine, but when i rev it, or try to drive, it completely stumbles on it's face. It sounds like it is breaking up, and wont rev any higher than 3k.... But then sometimes it is perfect and revs fine.

Does anyone have a clue what this could be?

Since you have a 4 cylinder car, post your problem code in the 4 cylinder forum. Someone there may have an explanation.
