Tonight after work i checked my ignition timing just for the heck of it. At idle with the car fully warm, it was advanced!!! I pulled the vac hose off the ignition advance and there was no vacuum! Just a popping kind of sound when i first removed it, but no sucking. i put it back on, checked the timing again, it was back to normal. it seems like it is going back and forth on its own. the solenoid is new. what gives? i redid the wires on the idle speed switch and they aren't loose anymore. what is going on here? how do i hook up my multimeter so i can tell if the switch is operating correctly? it is being engaged and disengaged when it should be. i'm really confused now....
