Unusual Vehicle Behavior

So, i'm probably in a fail situation here, but here's a couple points before people tell me to go to the dealer:

1. I'm over 50K miles
2. The problem is just like the engine ticking nonsense. It's practically impossible to replicate for the dealer because it happens randomly


Alright, onto my unusual vehicle behavior.

This isn't the first time it's happened, but it's happened only a few times at random times.

The very first time this happened was when I got off the 22W freeway and started heading to a bakery in Garden Grove.

I had my windows down, and when i let go of my acceleration and let my car slow down for the right turn stop light, you can hear this very loud whistling noise. It disappears or becomes mute when i start accelerating again.

Later down the road, I start slowing down for a left turn stop light. Same noise as I reduce speed. Once I completely stop, the car starts acting really weird.

It starts increasing RPM repeatedly in short bursts, and I can feel the car pushing itself forward when the RPMs increase. I had my foot on the brakes, but i know if i didn't, my car would force itself into the car in front of me. I wish I could take a video of this, but I never have my digital camera with me when it occurs.

This happens to my old '93 E34 5-series too. 525i.

Anyone have any clue as to what's happening?
