I know all about 4.6's having loud injectors, my tbirds injectors are pretty loud. Now on my stang that I just bought in april I've been hearing the famous ticking but it is really loud. So I used the stethoscope thing to pinpoint exactly where. I hear all the injectors but there is one that is much louder than the others. Is it normal to have one that is alot louder than the others? Its starting to really get on my nerves so maybe I could just replace that one? Any info would be nice. Thanks.
