i have a 94 celica gt, and sometimes when im slowing down, not just pushing in on the brake, but just letting of the gas, or have the clutch pushed in all the way and coasting, my car makes a kinda of a scraping noise. it sounds like the whole car is doing it. it doesnt do it all the time though. i cant figure out what it is, and i was hoping maybe someone had it happen to them and can tell me what it is.

try putting it in neutral then coating,or try to like swerve and see if u can change the noise
