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.
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. :)
