Default half-throttle

Hello all,
A problem just started today with cold-starting. I have to give it half the pedal for it to fire off. Hot starts are fine. Any clue to what it might be?
thanks,
Kevin-n-Laura

Kevin,

I looked for the idle switch here and couldn't find it. Maybe you will have better luck.
