ea82 idle switch questions

Recommended Posts

the two conditions the manual gives for timing adjustment are...


1) test mode wires connected


2) idle switch must be ON


...ok, the test wires are simple enough. But now the questions...


What do they mean by the idle switch? Is this something I'm supposed to DO, or something the car should do itself and I just need to CHECK?


Do I just put a multimeter to the idle switch wire of the TPS and check for power? If so, I don't have a DMM...would a 12V test light suffice?
