Hi everyone!

My name is Chase and I'm new to the forum. I am the proud owner of a 2005 R53 MCS and a 2003 E46 325i touring. At a stoplight yesterday, I noticed an odd idle pattern/inconsistency. The car was completely warm and I had been driving for about 30 minutes. It was intermittent; the idle did not surge every time I came to a stop. However, it happened frequently enough that I figured I would look into it. No effect on drivability. I will attach a video I took in a parking lot to demonstrate the problem. Any ideas or past experiences with this issue?

Thanks!
