Hi I just want to so thank you to this site. By D would still be in the garage if it was not for you.

So here is where i am at. I am having a problem with my cold starts, and after it has been sitting for a while. I start it and then i just dies out. If i play with the gas peddle it will sputter for me(about 1 minute) then once i hear the frequency valve kick in, the car start running correctly.

I have replaced the fuel pump, accumulator, fuel filter, o rings in fuel distributor and even added a second check valve by the fuel pump. I Cleaned the warm up regulator. I even took it apart and clean the o ring diaphragm inside. Put it back together and that helped a little. Then i tried adjust the mixture control valve right next to fuel distributor. (1/6 turn cw) This helped when the moter was warm, but made it worse when the motor was cold.

The car had been to a garage once to have the mixture adjusted and this made it pass CA smog. So i think the distributor is ok with its settings.
I clean the idle speed motor and made sure if was free moving. Then i tested it and made the flap inside move.

I am not sure where to go from hear. Should i clean/replace the frequency valve? Or is it the lambo board not sending a signal to the valve?

Thank you for the help
