I have a really sharp buzzing sound coming from my 2006 Nissan Altima engine. The sound starts and stays around as soon as press the accelerator. Doesn't go away until I turn the car off. I know there are similiar issues like this but didn't know if the acceleration part hints at a specific problem.

Does the problem happen at idle? Does it happen if the vehicle is placed into neutral and gas is applied? How many miles are on the vehicle? Does it consume any oil? Any other symptoms you're feeling? – cinelli Apr 3 '13 at 0:56
After the first acceleration it happens at idle. The only time after the acceleration, the sound goes away is by turning the car off. Car has about 80k miles. No other symptoms I've noticed. – KingKongFrog Apr 3 '13 at 1:47
Have you made sure that it is in fact coming form the engine? Pop the hood next time you get it to happen and see if you can locate exactly where the noise is coming. Front / Rear / Right / Left of engine. – cinelli Apr 3 '13 at 2:01
Coming from passenger side of engine. – KingKongFrog Apr 3 '13 at 4:07
Have you checked the oil level? If you've had to add any then how much? – cinelli Apr 4 '13 at 4:44

After digging around I read somewhere to try another brand of oil filter. I was using a cheap one when I noticed the buzz. Once I used a higher end filter, the noise magically disappeared. :)
