Won't idle

[thrude1]

Has anyone run into this issue before I have a 2017 hd10 just finished washing it and now it won't stay running unless I have the throttle all the way down and it's really smoky if I try starting it without full throttle it turns over but won't run maybe the fuel filter but idk why this would all of a sudden happen after washing the machine

Does it go away after it dries out? 

If it only happens after you wash it, I would say water is getting into something, probably electrical, and causing problems. I'd start by checking fuel pump plug and ignition electrical plug, check the seal and see if there is water in the contact area. Add dielectric grease to your electrical plugs.
