okay starting about three days ago every now and then i hear what sounds like something stiff letting loose and it makes a knng noise....haha, hard to impersonate sounds with a keyboard. anyways i'm thinking its my front drivers side shock (tokico blues with eibach pro kit springs, been on for a little over 2 years). i'm hoping its just a shock getting old because it seems to happen when accelerating or decelerating. but it doesnt happen that often. i just upgraded and i'm running 9lbs of boost so i really hope its not something in the engine. oh i'm running rich with the timing retard as low as it can go so i should be running this boost safely. this is a '98 civic ex by the way. tell me what you guys think.
