start car, let it get to operating temp.
pull TPS plug (just the main one, not the switch --- for auto cars/obd-2)
adjust idle via screw on back of intake manifold to within 750 rpm idle (+ or - 50 variance).
loosen distributor, hook up timing light.
check timing. adjust as needed. stock is 20* (stock sr is 15*).
bolt dist. down, plug tps back in. drive.
there you go. couldn't get more simple or accurate. and it saved you some searching.
have fun
