Thanks for the responses.

I checked for vacuum leaks before and found a couple and fixed them. I have a new CCV, but I didnt replace it yet because after I fixed the vac leaks it started running a lot better. Maybe the CCV is the source of another vac leak?

I cleaned the MAF with MAF cleaner already, but didnt test it.

All 4 O2 sensors were replaced by PO at 100k.

T stat was replaced at 70k in 09, time to replace again?

Question: When I first start the car in the morning, it fires right up, and idles smooth. Then about 45 sec later, i hear something that sounds like a gurgling sound, and or a valve closing, then the idle speed goes down a little, almost too much because then it starts idling a little rougher. Any ideas on that?

oembimmerparts--I had already checked that plug and it looks ok. I didnt disconnect it though.
