    90 mph makes a quick noise like going over center lines!

    First thing when I get to about 90mph I hear this sound in the rear as if I'm going over the line on the freeway but it stops once I either let go of the pedal or hit 95mph. What is it? I thought it was the exaust because of the certain vibrations but i figure it would happen if i hit the high rpm in the lower gears. Another problem is when i get to about 110mph it begins to jult as if it loses power? does it need an ecu?

    first thoughts....You got funky tire tread on those back tires.
    Do you rotate your tires every oil change? I can almost guarantee that's the problem with your speed "noise" at certain mph's. Check out your tire tread on the back tires. Hope this helps. Good luck!
