Adjusting the idle
Setting idle while engine is on. Disconnect the TPS. Turn engine on and adjust idle screw. Your idle will be 50 rpm lower with TPS disconnected so shoot for 650 rpm to get 700 rpm. Make sure engine is warmed up and your base timing is at spec.
Turn the idle adjusting screw on the IAA clockwise to lower idle or counter clockwise to increase idle. The IAA is at the back of the intake manifold by the firewall passenger side. You can see it standing over the passenger side wheel . Use a flashlight. Your beloved should purr at 700 or so rpm. (The Factory manual gives a +/- tolerance of 50 rpm.)
