I just bought a 2012 LT with 94k I didn’t notice anything during the test drive but when I got home from buying the car is when I noticed the thump knock low tapping noise it’s hard to explain it doesn’t sound like spark knock or lifter noise or rod knock it’s only noticeable under acceleration and stops when the car is shifting then comes right back after shift also doesn’t do it at idle and when reviving up in park anybody have clue as to what this might be?
