Sorry Chuck, I was thinking these were CIS with the flapper door there in the middle of the valley. Good point about the cold start leaking. I've seen injectors that were dirty and dripped after the car was shut off too. Then the carbon on the backs of the valves and the tops of the pistons soaks up the fuel. When you go to start, you're temporarily flooded while all the extra fuel burns off.

Glad the BG helped. It's the best fuel injection cleaner on the market. Use it every few months, and you might hold off on replacing anything until you run a tank of fuel through it. Then see how it is.
