F115 Idles problems

[Oz Slider]

I have a 2003 Yam F115 on a 19ft Polar CC. It opens out to WOT great, but when I come back to the dock and I am in idle, she wants to stall every time. She idles like a dog after a day on the water. Like most, the mechs and dealers dont want to deal or dont know.... Any help would be appreciated......

That can usually be corrected by adjusting throttle position sensor and idle speed by connecting engine to computer diagnostic system. The engine has to be warm when making adjustments.
