I started hearing a louder clatter in my eng about two weeks ago and just blew it off as colder temps in the morning. Well it blew smoke at ambient temp of 65 and when I accellerated it smoked blue a little heavy so went to shop and disconected Edge Ez and no more clatter and no more smoke. What the heck is up with that?Also my boost elbow is still hooked up, I have not thrown any codes yet, should I leave it hooked up or is it defeating it's purpose? The last time I left it hooked up it kept throwing codes.
