Clicking noise from wheel or under-car area?

[05PhillyStang]

Has anyone noticed a clicking sound coming from underneath their car? It can be heard with the windows down. If you get on the throttle, it gets drowned out, but if you are slowly accelerating from a stop, you here a "tick-tick-tick" noise that gets faster as you speed up. It's driving me nuts!

At first, I thought it was coming from the wheels, but it may be from under the car. Has anyone experienced this?

Or worse yet--a nail or screw head.

No, none of that. I checked the tires for pebbles or nails and found none. I even had friend walk next to the car as I drove slowly. Then he drove and I walked...Nothing. It's not the A/C because it's always happening.

It kind of sound like there's a plastic tag flapping behind the wheel. Almost like when you put a baseball card in your bicycle as a kid, but much, much less noisy

really sounds like a rock or nail. jack the car up and spin the tires to check thoroughly.
