Initial Cold Start Stall Out

[dshscarab]

Hello Everyone.
I have a 2019 AR-195. Lately, when the boat has not been used for approximately 3 to 4 days, Upon starting the boat, it stalls out. (doesn't want to idle). I have to restart and immediately give it some gas to keep it running until after a few minutes. Does this happen to anyone else? I don't remember the boat doing this before. It may have started after I cut the Ribbon out of the manifold. I wonder if there is a very small leak???

Different boat, but when it happened to me replacing the plugs made the problem go away. Plug replacement is cheap enough it may be worth it.

Normally, I would agree with @Beachbummer , but on a 2019 right after a ribbon delete? I would check your delete job. Make sure everything got seated properly when you put it back together and nothing got kinked.

Thanks. I think it was right around that time of the Ribbon Delete. If you remember, it is a one piece design for 2019 and I actually had to cut it out. I must say I don't smell anything. Once the boat warms a little, it idles and runs perfect. Just the initial cold start like the ECM isn't adjusting.

Beachbummer, I changed the plugs at 10 hours. I now have 45 hours on them gaped at maximum. I do use the Sta-Bil 360 in the tank mixed on the strong side. I suppose between the two, it could also contribute.
