Trash the Chiltons. It's in the fsm, either in the fuel section, or maybe engine control.

I just set the throttle cable just short of tight with a warmed up engine at normal idle. The procedure you are trying to do is to set the tps so the idle switch is set right, and you set it AFTER you set the mechanical base idle.

Are you grounding the timing connector before setting the timing?
