I had the EXACT same problem...and my car would die if if let it idle. This happend to me typically when my car was cold...

It turned out my entire VANOS system was bad...the VANOS gears were worn and they replaced the VANOS system and the VANOS ECU. It was under warranty thank god...otherwise it would have been $$$
