I checked everything in that general area and nothing seemed to be loose. I just thought that maybe there was a reason why Ford used a plastic valve and not a metal one. My thought is that the metal valve is rattling when the air stream goes thru it causing the noise. I really have no clue. I also pulled off the accordian tube going to the TB and couldn't see anything loose in there either. The two screws holding the TB on were tight as well. I just really want this annoying noise to go away! Thanks for all your help and advice!!!
