need help with bucking
 

Hi guys, well I have always had a little bit of bucking since i have installed my f-303 cam, but lately it does it alot more than usual all the way up to 2500rpm.. What is causing it to do this? Its a mass air converted car with a new granatelli 75MM mass air meter.. i reset my computer the other day and re did my timing but it seems to be a bit worse, but I always had this problem... any idea's? Some one told me my stator might be going in my distributor... any thoughts? Thanks guys!
