Ok so i tired taking my car out today, it was hard to start, then when i got it running it would go, then violently buck adn teh knock sensor off, it did thisfor a second, then everything was fine, it revs freely fine, then i tried driving again, boosted a little everything was fine, then I was just going lightly on the gas, not even boosting adn it did it again like 4 times in a row.

Since my fuel level sensor is fed up since I did my pump install maybe I am just really low on gas? Even though I dont think that is the problem I might try ptuting some in.
