ICV Question

[318ls]

I accidently placed this over in sales Forum, but here it is:
Hi all, I have been enjoying my m42 for over 3 years now!  Until a month ago, my baby suddenly quit on me.  After a couple weeks of diagnostic, I find out the crank sensor went to hell with over 1.5M ohm read on my DMM!  Thanks to REDHEAD and M42Club, I was able to get another sensor and she is back to life.
Although my baby is running again, she starts to bounce her idle from time to time, cold or warm; mostly from 1500 to 2K.  As I was cleaning out my ICV, I notice the gate within the valve have a gap and kind of chipped up.  I wonder if that could have created a vacuum leak through the valve.  Here is a picture of the gate itself!

Like I said, I don't know if that gap suppose to be there, please advise-
Thanks guys...

I just replaced mine and looked at the old one. It's flush, so I don't think those chips are supposed to be there. Based on that and the fact that a bouncy idle is usually and indication of a faulty ICV, I'd say yours needs to be replaced.

I can send you my old one for the cost of shipping if you want to try to rebuild it.

It's been a few more days after I cleaned out the ICV.  I notice the idle still bounces erratically.  Do anyone have an extra working ICV that I can buy from?
