I just purchased my Uncle's baby back in September 04. The weather was warm and it started every time I turned the key.

Ever since the weather turned cold in Central Ohio it cranks for a very long time and after a lot of sputtering, it finally kicks over. Once it's running it goes pretty good.

I read in the Chilton manual about a "Cold Start Valve" but the manual does not show where it's located.

My first Q, could this be the culprit and if so, where the heck is it located?

Welcome to the BenzForum Community. The SL is a great car. See your post in the Tech board for a link to a photo of the cold start valve.

Thanks for your help.

After seeing the part I was able to see where it is.

When my wife is out of town I'll order the part :mrgreen:
