The car has had this odd squeal sound for about 1.5 years. It only happens once in a great while and only when accelerating from a stop(fast or slow) in first gear when the engine hasn't fully warmed up. I was lucky to catch it on video yesterday, so I thought I'd post it to see if anyone knows this sound. I realize that getting to the root of the problem is going to take some hands on investigation, but any ideas on where to start would be appreciated.
I also have a CEL which popped up 5 months ago...codes for secondary air injection P1411 and P0410, but this sound started a good year before the CEL, so I'm not sure if they are related.

Thanks in advance for any info
