I have cleaned the IACV, but I will recheck this weekend! As for the TPS I found how it works on the maint CD! Appears that the one on the intake portion is for WOT measurement! Only at WOT is the resistance 0 then it is infinite all other times. Then there is the other switch on the actuall throttle linkage! That is 0 Ohms at idle and infinite otherwise. They used two diferent things to determine it on my M102 engine! Go figure. I am thinking my idle that I feel is simply due to needing new fuel injectors! I have cleaned them by soaking them in carb cleaner and run several bottles of Techron through. I just put in two bottles of Lucas to try that! It normally runs smooth as silk when using the Techron, but I would have to add to each tank so I am assuming the injectors just need replacement. It runs a hell of a lot smoother than it did 4-6 months ago so I am gaining I guess. I am going to play around with the IACV this weekend while the wife is away on Sunday! I want to unplug it and see if she idles smoother! If so maybe it needs to be opened up a hair. All it does when you turn the knob is raise idle or lower depending on which way. Of course after adjustment you need to adjust mixture to compensate for more or less air. One of these days I will get it! Maybe I just need to get a new one, but they are a little pricey!!!!!
