I honestly might have been. Still new to all of this and getting to know my car better. Car did have a real rough idle occasionally and had a few times last few months where power and rpm stumbles for half a second at lower speeds. Never had a CEL tho, I'd assume a misfire would trigger CEL? Or only after it's a constant issue?
