several things could be wrong are you using 91 octane fuel or less? also it might be a timing issue you might be too far advanced in timing ... this causes preignition.. causing a rattle also cheaper fuel will do the same effect.. thanks Jerry holler if you need more.. also was the noise loud or just a mild noise ??

that sounds like what we call "spark knock" that occurs when u accellerate quickly, but yes it will go away in a few seconds when the computer detects this condition. with the economy the way it is it will be more expensive, but try running higher octane gasoline in it, should cure this condition. hope that helped you!!

First thing i would try...... ISOHEET, Red bottle..... allows water to be mixed into the fuel and be burnt out of the tank.
get a good qaulity fuel injection cleaner, if you can locate the brand MALCO, i found it quite succesful..... and go with a full tank of premium fuel such as ammoco or shell......do not use yellow bottle of heet
