It could be the dreaded center stack rattleKind of between the rear of the engine and the footwell. In the area of where the cat heat shields are. Doesn;t look like there is much you can do with the shields though?? I noticed how flimsy they are during the shifter install. I have some hearing issues so sometimes its difficult to source a sound, but can hear it. If that makes any sense:headscratch: The best I can tell that is where its coming from.
Let me know... I'd thought Ford had fixed this on the newer cars.You may be right. I think I have a loose exhaust coupler at the H-pipe / exhaust pipe jount. Saw some condensation dripping at the face of the clamp during shifter install. Forgot about it until today. Should be able to check the TSB when I check the clamp. If it is where I think it is.
