Even though you hear the micro switch clicking it still may be defective. You should check it with a continuity meter and also visually examine the wiring and connecters going to it. It could be a corroded contact in a plug or maybe the micro got wet and is rusty inside. When the micro "kicks in" you should hear a noticiable change in the idle of the motor. The idle motor has a low failure rate so you should be checking everything else before condeming it. Also check that the throttle just makes the switch click, if it bangs the switch that could damage the insides of the micro. Check fuse #1 10 amp. Refer to workshop manual M:18:09 and go through the circuit component by component.
