Well, this is a new one on me.

I was actually working on the sunroof and checking the torque.
I had the key in 2, engine off, and I noticed idle speed adjusting wire that goes to the dash was smoking (under the hood).

It was too hot to the touch. I felt around everywhere else on the linkage, but nothing else was hot.

(my first guess is that a wire is touching the glow plug wires)

Is this something simple? Or did I do something wrong?
