Thanks, thats good to know because I havent run it past 75 in months after a nice little speeding ticket I got log before the problem started. So I don't think I have been runing to hard. Which gives me cause to look at other possiblities more closely. Since the symptoms of a cracked piston aren't blatant it makes more since for it to be somthing like a vac leak or plugs, but until I'm sure I'll just try evrything and anything you guys can suggest.
~ cuz I love this car and hate to see the engine shack and jutter like it has~
