I have a 92 9500, with three position idle switch...when I first start up in the morning all three positions work...then after everything is warmed up after combining for an hour...it will only idle down to 1660 rpm. Doesn't matter if it's in the middle or lowest switch position.
It's not showing any codes...any ideas?
