Your VIN is a 500 SEC.so it should have the electronic idle control.
Do you have the diagrams for the vacuum lines to WUR?.It's pretty important that it's connected in the correct fashion because warm up ,aceleration and general running depend on it. All of the WUR's are stamped made in france. The last three numbers of the part number should be 101. it must also have two lower connections and one large top connection.
I see from your pic that the plug leads are looking old, if you have access to a multimeter,check the resistance from cap to plug end. They are very sensitive to correct plugs and good leads.Another reason your car will be hard to start when hot.
You also have the rubber cover over the distributor cap. LOSE IT! Mercedes don't even list that as a part anymore because of the problems it causes.
Everything from moisture getting trapped under it,to dirt causing static electricity causing spark leakage.

I just replsced the distributor cap & rotor
cap I got is same as one on it...???
The euro is a beast
I hope that I got the correct one
I don;t have ;east I dont think I have a rubber cap on distributor cap.
I have bought NGK BP5Es plugs & bosch prem ignit wires
& I am going to have a mechanic change
I;m no mechanic
but got the distrib cap & rotor done
I have been changing out old vacuuum lines on WUR & anywhere I can
the WUR
has 3 vac hses
one on top which goes to a port off the thermo ICV
one in front I cant trace
& one in back that leads to a t vac hose that the bottom of goes into a 50C thermp vac awitch
thern goes to back intake manifold
the other line on the double TVV goes to that quad hose in front
which one leg goes to distributor valve another to that yellow & green air inject valve which leads into intake manifold
I rteplace most of the vac hoses
some were cracked or broken & thet yeloow green valve was discionnected
Now that I broke the TVV
I have connected that loop together & bypassed the tvv
