Cold hesitation is normal??
I finallly got my 85 380sl running almost like new.. I replaced (cap, rotor, wires, plugs, coil, ICV, CSV, OLV relay, fuel pump.) and still had the cold start and running rough problem. Finally bought the car to a mechanic recommended by the forum. It turned out to be a mixture problem. He adjusted the 3mm screw and run prefectly. However, after I get the car started, I press on the gas and it also stalled. Let go the gas and idle prefect. I asked him and he said it is normal during the spring time (50'-60' deg) Once the weather gets warmer, the hesitation will be gone.. He also said if I replaced the warm up regulator, it may improve a little bit.. Anything else I can do?????
thanks

Cold hesitation on that engine can be elimated with the correct fuel pressure adjustments! ON any CIS engine with warm-up regulator the fuel pressure MAP is temp controlled and must be with-in Bosch specs thru-out the warm-up process!
Many times a new warm-up regulator is required, BUT many times even a new regulator will require slight adjustment.
