When I'm at speed I'm hearing what sounds like a tambourine. The sound is seems to be most likely coming from the engine area, though it is a bit hard to narrow down with road noise at 55 to 60 mph. This only happens at speed.

It's a 96 EX auto by the way. Have any of you encountered something similar?

 

Something is most likly lose and rattleing around have a look and see if you can vissualy see what it is.
