Had this error code come up. Changed all the spark plugs while I had the manifold off. Changed the No. 3 Coil with brand New OEM and all the vaccum lines on the manifold. Intake Gasket is fine no leaks. Only had a slight ruff start only when starting engine. Drives fine. No other code other than the misfire on No.3. Everything else is fine. Now what can it be?
