Hey all, I’ve got 30k on my 3.6 rubi, and I’ve noticed sometimes between 2nd and 3rd gear around 2k to 3k rpm, I’m getting what some are referring to as “spark knock”. No loss in power, just sound a little like a diesel for a couple turns. I’m running shell 91 and it seems to help and but. Has anyone figured out a solution for this? As it seems FCA acts like it doesn’t exist.
