Quick update in case anyone is having a similar issue or has it in the future. The “shuttering” has been tracked down to being the fuel pump. It sounds like a physical knocking noise. It only really happens between 1800-2200rpm. It does it even in park or neutral.
The dealership who sold me the Jeep is saying that the new JL fuel pumps are louder than JKs and the reason I hear it is because I have a 2door and the tank is a lot closer to me than a 4door or gladiator.
If it’s truly the noise it makes then I’m cool with it, it doesn’t bother me. I’m just more worried I bought a defective vehicle. If any one also hears it or has any experience on the topic I’d appreciate any advice.
