Cold start stalling

[Chris216]

GG, thanks, I haven't run a fuel system cleaner (I use Berrymans chem tool B12 in my other vehicles) thru the 1250 yet, I'll give that a try. My local station typically (no guarantees LOL) has the best fuel in the area, non ethanol premium 91 oct. But I'll have to give that a try. Thing is that once the first cold  start is done it runs fine for the rest of the day. I'll take a look at the plugs and see what they look like.
