This morning when i start it up...it was cool but when i start driving it...it made this vibration and scratching sound under my hood. At first i thought it was the brakes and stuff. I later found out it wasnt the brakes. The sound and vibration comes everytime after i start the car and it doesnt make the noise at idle...only when i drive the car (within the first 5 seconds and the sound/vibration only last like 2 seconds). After that, it runs like normal.

I did this 5 times:

1. Start the car
2. let the car idle for 30 seconds (everything seems normal)
3. Put the car in D and give a little gas (at this point within 5 seconds...the vq vibrates and makes a scratchy noise which last about 2 seconds)
4. Everything runs normal and smooth afterwards...no noise or vibrations...no lights

Anything wrong w/ my ride? I assume it is from the engine...
Thanks in advance
