You are correct about the a lot going on until the engine gets to normal temp.

I have found that the dealer here does not do well with cold starting injection problems so I will sort out this puzzle a piece at a time. I had a 1964 230SL and managed to figure out how that injection system worked.

I have subsribed to the Alldata.com/diy service support for this car and there is a lot of good information on service documents, repairs, and diagnostics.

With the excellent help of Bob Terry on this foum and the Alldata information I was able to get my hard top operational with a simple 10 minute procedure. Prior to help from Bib I had paid the dealer $175.00 to mess around with it.

I am confident that we will get this problem solved as well.

Please stay tuned.
