Have you tried pin pointing it with a mechanic's stethoscope? Or you can use a length of fuel line to your ear and listen with the other end close to the noise. You can spot exactly where the noise is coming from.

Also, when was the last time you did a tune-up. If its been over 50K miles, replace plus, filters, and pcv valve.

It's just a SUPER-DUTY Mustang GT Sedan. 198K miles and still rolling HARD.

1997 Crown Victoria P71 SVT *** ex-US Marshall service (the CAR)
STOCK?? I bet it was modified.

13.26 @ 107.24 MPH 1/4 mi w/ me, tools, & full tank of 93 octane

I added CAI, NICHE 19 X 8.5 " wheels with 245/45ZR 19 rubbers, and completely rebuilt the front end with poly bushings, Kooks headers, 2 1/4inch exhaust, TCI 2200-2400 rpm Stall converter

.PLANS:: engine upgrade, 5.4L 2v stroker, rebuild interior in leather w/ buckets, thinking about turbos

Wow just ran across this post nosing around and by golly the youtube video that is pointed to is one I made on my car and is in my account. I can only hope it is being used as an example which is fine. Just curious however.

Oh FYI solved this: AC Clutch
