Steve i need your input on this. I have an 88 300E and just replaced the fuel distributor. i want to adjust the mixture screw. What is the process. I do not have duty cycle meter but I have a good Ma meter that i can hook to the eHA actuator. What are the steps to follow? Do I need to have the engine at operating temp? Do I need to disconnect the Oxygen sensor? Finally what current should I aim for at the EHA? Is this current with the O2 sensor disconnected?

Thanks in advance.

PS: This is an 88 300E California car.
