The "clock spring" is actually a spiral of flat wires that
winds around the steering shaft and connects the electrics
to your horn, cruise control, and airbag.

Well, no leaks around the base of the TB, sprayed that slot out really
well, but still no dice. I'm getting a full tank today and will put

PCM update about rough idle upon cold start.
Not giving up yet :)
thanks
