| WHOA! before you think that far. break out a voltmeter and check for pre sence of voltage in the ICV line(with engine running). If yes, the u are fine. No voltage present, then i will still suspect IDLE CONTROL MODULE.
ICV inspection: idle control valve must be open when there is no voltage applied. I suppose you have the 2 prong type-there should be a 40 ohm resistance between the terminals. if 40 ohms is not attained, replace ICV.
* pinnaclebass: you might also want to rule out the thermo time switch on the t-stat head. Procedure will be to warm up ur car to operating temp and then disconnect the brown sensor. let's see if the erratic idle stops with the sensor disconnected.
I wish to know as well whether the erratic idle happens even with a warm engine. (you just might have knocked off a connection to ur cold start valve while trying to rest ur lights) ;-)
