    06 STS V-6 engine issues....

    The other night on my way home, running about 55mph. I decided to drop the hammer. When I had to stop at a light, the engine was idling rough and missing. No dummy lights came on. Only a few blocks from home, so I continued to drive home. As I drove in drive way, engine was running normal. Has not duplicated since. This morning I had a low coolant light. I had a low coolant light a month ago and topped off then. I've owned the car over a year now, and been running like a champ. So now two coolant light and less than a month. Inspected engine/radiator/hoses and can NOT find a visible external coolant leak. Do I have a head gasket going bad? Also not seeing white smoke out the tail pipes.

    Was the coolant cap tight? How is the oil level also?

    Cap is tight, and it does have a small oil leak on passanger side of engine. Gonna be taking it into dealer soon, but trying to get ideas. I put 2 quarts of oil in last 5k miles. Oil% at 40%.
