I hear rattling noise under the car engine. It starts when accelerating at 15 to 30 miles and then stops after about 2 minutes when acceleration is increased. The check engine sign shows sometimes but goes off later. The use of a diagnostic machine indicated there was nothing to worry about the engine. Your expert opinion on this would be very much appreciated. Thank you

Check the belt and tensioner it may be your problem then if a code see what it is normally if it's nothing to worry about its' a gas cap but other than that it should be fixed.
