Popping noise from exhaust on cold start

AdventureNoodle · 10-22-2022, 04:49 AM

Recently started happening and no idea what it could be. It comes and goes as the car idles in neutral. Did plugs like 100 miles ago, didn't fix the issue. Anybody have any idea what it could be?

I’d be curious if it persists after flashing back to stock.
