Hey,
I dunno, this happened for the first time. I turned onto a street where the limit is 100 and as soon as I hit between 100 and 105, I hear this LOUD wierd noise. Sounded like I had a flat tire or something. It was like a piece of plastic or rubber hitting against something real hard. When I pulled over to the side to see what it was, I couldn't find nething? I suspect that little underbody plastic engine cover near the front bumper to be problem, but funny thing is after that incident, I travled on the highway and no noise? I even hit 120 and no problem. Does neone know what it could be and or if that was the problem? Thanx

 

somthing might be off balance.
almost everything that is on a car is baleneced, like the motor
wheels even your suspension, and the way its on your car creates a balace

 

maybe your fender liner fell and was dragging on your wheel??
