Hi,

I have a problem with an occasional rough idle or engine stumble and I have seen posts from others that also have this problem. Sitting at a light...engine idling smooth...and then it stumbles for several seconds...then smooth again. I do not know if anyone has found a cause for this, but I am interested if you feel that you have a solution for this problem (minor problem...but would like a smooth idle all the time).

Also, I came across the below service bulletin for the Mercedes slk320...same engine as the Crossfire...Has anyone seen or heard of this before? Does anyone know of any TSB for the Crossfire that addresses this?

Andrew and STRYFOX...What's your take on this? How can we find out more about this bulletin and whether or not our Crossfires have the updated software discussed below? Comments and experiences with this problem from any crossfire owners welcome.

Thanks
