James, You can test the TTS switch and the cold start valve real easy. Just remove the cold start valve and lay it on a piece of card board or something to see the small amount of fuel sprays when you turn the key on like trying to start the car. Just a second. If they are working OK, then the air flow meter may need a 1/8 or 1/4 turn clock. The control plunger is riding to low in the fuel distributor. Have your CO checked when you can with the proper equipment. John hervey http://www.specialtauto.com/
