During acceleration (not super light feather) loud buzzing noise coming from passanger side of engine compartment, and seems to be more pronounced after the tranny shifts into 2nd. Took it in for a leaking radiator (replaced, $350 later) asked them to find out what was causing the noise. The garage was unable to find a cause, but did hear it. Thought at first it was a tranny issue, some sort of line buzz but no evidence of it was found. They also checked for some loose parts under the car and under the engine compartment, again no dice. It doesn't appear to be causing any issues but is driving me nucking futs. Any thoughts on this? It does not sound like pinging/detonation at all, and since its on the passenger side it doesn't appear to be the ac pully/compressor or belt. I am at a loss and don't want to take it to the stealership yet.

Thanks

 

have you checked you cat, and heat shields?

 

Mechanic was under the car for some time checking for anything loose or otherwise obviously able to make such a buzzing sound, no dice. I suppose it could be a cat will have to mention that next time it goes in.

 

Had this problem on mine after putting in subs best buy told me it was because of cheap rca cables? Just a thought.

 

I wish it was due to stereo equipment, it sounds like its coming from the outside of the car, not from the interior.

 

so did they check the fluiod on the tranny?

 

maybe a noise with the bpipe in the exhaust..

 

When it was in getting the radiator replaced the tranny was checked as the tech heard it when I drove him around. He mentioned to him it sounded like an issue with the tranny, but upon further examiniation he said it most likely wasn't as there were no signs of any tranny problems. So at this point back to square 1.

 

Wouldn't that mean that when its in park and I rev up the motor it should make the noise then, which it does not.
