Currently need help with my vehicle. I’ve changed the spark plugs, spark plug wires, ignition coil pack, valve cover seals, intake manifold gasket, cleaned my throttle body, etc. My car starts up fine and runs perfect when it’s cold. When it starts to warm up it starts to sputter / putter air from the exhaust. I code scanned it and it read cylinder misfire #4. I have no signs of a bad head gasket, no milky oil, no exhaust smoke, nothing.
