It did the ticking prior and post plug swap so I ruled that out. Injectors I thought about, but it seems like it's on a specific bank, not "centralized" or coming from all injectors. A valve? That sounds expensive so I ruled that out (that works right? ) I'm about 98% sure it's an exhaust leak near the manifold and it does change speed with RPM. If I'm driving next to a Semi, a wall, or a high curb, I can hear it pretty loudly. Drive thrus are embarrasing

Let me know what the dealer says and what they charge you to diagnose. It would be much appreciated.

I'll try cleaning the TB this weekend.
