Agreed & misfiring or kncking is out of the normal. LT4’s motors are not known to be problematic within service as I rarely see them at work. We are a very large Auto Group. If the dealer Service Manager does not do anything I would write GM Corportare & if that recourse fails then get legalrepresentation. Lemon Law Lawyer would be the most viable course of action. I personally have been through it & the approach was successful.
