I have a 2005 z71 I was a ford guy so this is my first Chevy.... And it starts up fine, no pwr loss, no smoking???? A cold start and does not knock but when it stands in idle to longer than 5 to 9 mins a knocking starts and after it rev's up after about 2 min's the knocking is gone??? It sounds like a low end knock not really sure cause when it does happen its always on the road??? Would like any input???
