ok, my engine is dumb... first of it has no power, when im driving, its now very slow, feels like something is holding it back... about hafe way through a gear it makes a vibrating/ raping noise, as my dad would call it. when i start it at first it knocks for like 5 seconds... when im driving and i let of the gas it decelerates pretty quick... its a d16y7 5spd. i just dont know... thanks
