The air flow sensor plate is under the air filter box. EHA helps provide the fuel as soon as the ignition key is turned on. When you turn on the ignition key, 40 to 60 ma of current should flow through its coil. Check the coil resitance, it should be between 15 and 20 ohms. If you have not touched this plate and the car was working with the current plate setting, I would not mess with it.

Cold start problem could be related to a faulty cold start valve, though there has now been some doubt as to when this valve should function, some say it works only in extreme cold weather, but as far as I can recall, my valve works in Houston, and I have not rechecked it yet, but will do soon. Infact, when you crank and you get close to 12V on the cold start valve terminals, the computer is trying to use it, and when this occurs and no fuel comes out, I would think that it needs to be replaced.
