So I'm driving back from Miami on I-95 and I hear this shhhhhhhhhhhhhhhhhhhhhhhhhhh sound and I thought maybe I got a large twig caught underneath, has happened to be before (altho never in FL). So I do the stop, backup, etc., shimmy, but a bit later, still the sound. So I park over in a desolate part of a parking lot and crawl down and look under, and see that this black plastic shield-like piece right under the front of the car fell off partially. It seems there are usually about 6 screws/bolts holding it up on the chassis or whatever is under the grill. So until I got home, I had to jerry-rig it with rope that I luckily had some in my bag.
Is this something that can be as easy as buy the part and get the car up and unscrew and screw the new one in? What it is even called... I just want to make sure this isn't part of some bigger problem. I can literally see part of the plastic near the screw/bolt holes torn apart.
