This just started happening on Tuesday. On cold starts (<10F), the engine will not idle steadily, is misfiring, and stalls. It will continue to do this until it warms up a little bit. It is behaving as if it is partially flooded, as I can smell raw fuel and revving the engine will eventually clear the problem. No codes stored in any device aside from the instrument cluster complaining of an SCP databus error. It has popped that code since I bought the vehicle in 2015. Not sure if it is a failing CHT, or if there might be a sticky or leaky injector.

A bottle of fuel system cleaner (Gumout with REGAINE) did WONDERS for mine after a plug change. Spend the fifteen bucks on this and if you see major improvement, then you have a carbon buildup problem, which is very common in these Tritons with mileage. Well worth the fifteen bucks and you won't hurt anything by trying it!
I'm suspecting a FPDM problem or a pump problem. I notice that the pump whines a LOT louder when this is occurring. When I get a decent weekend with nothing going on, I'll drop the tank and inspect the pump assembly.
