when i accelorate really fast, my engine makes this tinny noise, like a tin can being flicked by your finger really fast. i've heard this sound in just about every car i have riden in or drove, but i was just wondering what makes that noise and how i can get rid of it. another thing, when i turn right really hard, my front left makes a knocking noise. PLEASE don't tell me its my U-joints....PLEASE!! erik geerdink vin 4512
