Man, that cold start problem is still beating me up. It's really a minor thing, but it just bugs the hell out of me. I've tried everything I can see in the tuning tables and so far nothing has had any effect. It idles real well at 17.3 percent opening of the throttle plate, but when I blip the gas pedal it will then settle at 14.1 percent and the engine acts like it is just starved for air and will either stall out, or oscillate the engine speed slowly for about 19 seconds. Then the throttle plate opens back up to 17.3 percent and the idle stabilizes. Once the engine cooling temps reach around 100 degrees, then it doesn't stall, and seems much happier when the throttle blade wants to be at 14.1 percent.
Well, it's GOT to be SOMETHING! Just damned if I can figure out WHAT.....
