2004 SL500 Suddenly Started Idling Poorly......

I posted this on Mercedes-Benz SLR & SL Roadsters > SL-Class (R230) as well hopefully I will get a better response here. Thanks in advance!

2004 SL500 started idling very poorly after being parked for about a month and half. Was running perfectly before this... car runs fine on the road, only when stop and idling does it acts up. What is the cause of this?

Hmm

Thoughts:

* Try running Techron through the fuel system for a full tank.

* If the battery went dead, or the car was jump started, the codes need to be cleared so it can adapt.

* Possible hidden rodent damage.
