Hello everyone I'm new to the forum, I recently purchased a 2016 sierra denali 6.2L
It has 180K. When I accelerate at 2000 rpm it literally sounds like the engine is at full throttle but doesn't have the power it used to when I first bought it! It looses power going up a hill I feel a little vibration on the floor board by the pedals when I accelerate, I've taken it to a couple shops and one of them told me a faulty torque converter and another one that it could be the fuel management system! Thank you for taking the time to read my post any help/suggestions would be greatly appreciated.
