So, i have a 99 f150 4.6 with just under 100k on it. The truck is now shaking when in park and sitting at red lights just started this about a week ago. and now when under any load in the lower RPM ranges no matter what gear or spead theres a very loud and noticable banging noise coming from the back of the engine i think. when the window is down its even louder. it sounds like a big piece of metal flaling arouns and hitting the hood or something. I cant find anything loose so it may be internaly. I have no idea what it is and i was wondering if anyone has any ideas. and when it does this the truck shudders ALOT.
