ok well i figured out that that is a knock sensor code. make sense being im not running one. any reason the revs are rough and choppy meaning its not smooth.

Knock sensor buddy. might be bad, might have loose wire, or stop running cheap fuel....

A bad knock sensor wont cause a rough idle, it just wont detect knock. \

You have other problems my friend, the knock sensor is only the begining.
