On my 300E it is right beside the Fuel Distributor close to the engine block (See photo) It has a pale green top.
Zorin or anyone,
How do you test whether this cold start valve (pale green top) is defective or not?
My 300 TE would "sometimes" have a rough cold start for only the first half second to one second of cold starting in the morning. But after that, the idle becomes smooth. When engine reaches operating temperature, the idle settles a little bit over 500 rpm and is still smooth. I do notice that my gas consumption is only about 18 mpg of combined city and freeway driving.
