the Automatic Idle Control valve.
It is a silver metal cylinder mounted just above the thermostat housing on top, front of the engine, with an electric connection on the top and two black rubber hoses coming out of it on the bottom (one straight out the bottom and one to the side).

Remove the AIC (remove the electrical connection and the hoses), and get a can of 3M throttle body or fuel injection system cleaner. Turn the AIC upside down, put on a mask, and spray a quarter of the can into the AIC holes. Let it soak in for a few hours, then repeat. A lot of black gunk will come out. Wipe it all off, shake as much of it out as possible, then remount the AIC and reconnect the hoses and electric connection. This solved the problem on my 900... the black gunk keeps the little silver door inside from completely closing or opening, affecting the mix. This only happened when warm outside.

Use the rest of the 3M cleaner to spray the throttle body itself, especially the throttle plate. This gets gunked up with soot as
well. To do so, remove the black flexible rubber air duct that runs to the throttle body from the air filter housing.

Best of luck with your new ride!
