Ous Es300 Dies When Cold -- Aux Air Valve Dirty?

[FredParoutaud]

Hi Folks,

Sometimes our ES300 just simply dies when it's cold.

My mechanic friend said "clean the Aux. Air Valve which is located on the Throttle Body"

Does that sound right? Can anybody tell me what it looks like? (I have a CD manual around somewhere -- is that the right name for the part?)

Thanks!

Fred
