sputtering when making boost
this is kind of a weird issue that popped up about a week ago thats got me scratching my head. when the car is first started is makes a weird puttering noise. you rev it up a little bit and it will stop. as you are driving it and you go over 3lbs of boost the puttering gets relly bad and nearly dies. i checked the vacume lines, just glancing over them and everything appeared ok. has anyone had this problem before??
